Are you tired of constantly adding more tasks to your to-do list in the hopes of being more productive? Well, what if I told you that doing less could actually make you more productive? It may sound counterintuitive, but hear me out.

As Tim Ferriss, author of "The 4-Hour Work Week," once said, "Being busy is most often used as a guise for avoiding the few critically important but uncomfortable actions." In other words, we often fill our schedules with busy work to avoid actually tackling the important tasks that will move us forward.

So, instead of adding more to our already overflowing plates, what if we take a step back and evaluate which tasks truly matter? As Steve Jobs famously said, "It's not about money. It's about the people you have, how you're led, and how much you get it." Prioritizing our time and focusing on the most important tasks can lead to greater productivity and success.

In this article, we'll explore the concept of doing less to be more productive and debunk the myth that productivity is solely about doing more. We'll provide examples and quotes from successful individuals to support this approach and encourage you to rethink your approach to productivity. So, let's get started!

Benefits of Next.js

Many developers are already aware of the benefits of using React for building dynamic client-side web applications. However, when it comes to server-side rendering (SSR), things can get a bit tricky. That's where Next.js comes in: it's a framework that builds on top of React to provide a streamlined server-side rendering experience.

One of the biggest advantages of using Next.js is improved performance. With SSR, your web application can deliver faster and more optimized content to users, resulting in a better user experience. As Jamon Holmgren, co-founder of Infinite Red, puts it, "The biggest are blazing-fast initial loading times of your site or app, and the ability to have a single-page app that works like a traditional website."

Another benefit of Next.js is its simplified development process. By providing a clear and easy-to-use structure for building web applications, Next.js reduces the amount of time and effort needed to get a project up and running. As a result, developers can focus on the core features of their application without worrying about the underlying infrastructure.

Finally, Next.js is a versatile framework that can be used in a variety of contexts. Whether you're building a simple static website or a complex web application, Next.js provides the flexibility and scalability to accommodate your needs. "Next.js is like a Swiss Army knife," says Chetan Agrawal, co-founder and CTO of Isomorphic Software. "It has everything you need to build a robust and scalable application quickly."

In summary, Next.js provides a number of benefits that make it an attractive choice for developers looking to build dynamic server-side rendered web applications. From improved performance to a simplified development process, Next.js offers the tools and flexibility required to build high-quality web applications quickly and efficiently.

Getting Started with Next.js

Are you ready to dive into the world of Next.js? This powerful framework has gained popularity among developers for its ease of use and scalability. If you're new to Next.js, don't worry – getting started is easier than you might think.

First, make sure you have Node.js installed on your machine. Next, navigate to your desired folder and initialize a new Next.js project by running the command "npx create-next-app". This will create a basic project structure and install all the necessary dependencies.

Once your project is set up, you can start exploring the many features that Next.js has to offer. From server-side rendering to automatic code splitting, there are plenty of tools to help you build fast and efficient web applications.

But before you start adding features left and right, consider taking a step back and evaluating what you really need. As Albert Einstein once said, "If you can't explain it simply, you don't understand it well enough." The same goes for your code – if you can't explain why a certain feature is necessary, it might be time to cut it.

By focusing on the essentials and removing unnecessary tasks from your to-do list, you can actually increase your productivity and build better applications. As legendary designer Dieter Rams once said, "Less, but better." So don't be afraid to take a minimalist approach and unlock the true power of Next.js.

Redirecting Users If They Aren’t Logged In

Why bother ? Isn't it easier to just let them wander aimlessly through your website, unable to access any of the cool features you've worked so hard to create? Actually, no. It's not easier, or smarter, or in any way productive to let unauthenticated users roam around your site. Here's why.

First of all, if users aren't logged in, you have no way of knowing who they are or what they want. You can't personalize their experience or offer them targeted content. They're just anonymous visitors, and anonymous visitors aren't likely to convert into paying customers or loyal fans.

Secondly, having unauthenticated users poking around your site can actually be harmful. They may stumble upon features or content that they shouldn't have access to, either because it's not finished yet or because it's meant only for registered users. This can lead to confusion, frustration, and even security breaches.

So, how do you redirect users if they aren't logged in? It's actually pretty simple with Next.js. Here's an example code snippet:

import { useRouter } from 'next/router'
import { useEffect } from 'react'

const LoginPage = '/login'

export default function MyProtectedPage() {
  const router = useRouter()

  useEffect(() => {
    if (!isLoggedIn()) {
  }, [])

  return (
      <h1>Welcome to MyProtectedPage!</h1>
      <p>This page is only accessible to authenticated users.</p>

In this example, we're using the useRouter and useEffect hooks to check if the user is logged in. If not, we redirect them to the login page using router.push. It's that easy!

In conclusion, redirecting unauthenticated users is a crucial step in creating a successful and secure website. Don't let them wander around aimlessly – guide them towards the content and features that are meant for them. With Next.js, the process is simple and effective. So, what are you waiting for? Start redirecting!

Code Example #1: Basic Redirect

Let's start with a simple example of redirecting users in Next.js. Say you have a blog that requires users to log in to read certain posts. You can easily redirect users to the login page if they aren't logged in using the following code:

import { useRouter } from 'next/router';
import { getUser } from '../utils/api';

export async function getServerSideProps(context) {
  const user = await getUser(context.req);

  if (!user) {
    return {
      redirect: {
        destination: '/login',
        permanent: false,

  return {
    props: {},

function HomePage() {
  const router = useRouter();

  return <div>{router.query.name || 'World'}</div>;

export default HomePage;

In this code example, we're using getServerSideProps to check if the user is logged in. If they're not, we're redirecting them to the login page with a permanent property set to false. This means the redirect is not permanent and search engines will not update their index to point to the new URL.

If the user is logged in, we simply return an empty props object. In the HomePage component, we're using useRouter from the Next.js router module to get the name query parameter from the URL.

This is just a basic example of how redirection works in Next.js. You can use this same approach to redirect users to any page you want based on certain conditions.

Code Example #2: Redirect with Custom Message

Now that we know how to redirect users who aren't logged in, let's take it a step further by customizing the message they receive. This is particularly helpful when you want to give users a specific reason why they can't access the page.

Here's a code example that uses the withAuth higher-order component to redirect users who aren't logged in with a custom message:

import { withAuth } from "../lib/withAuth";

const SecretPage = () => {
  return (
      <h1>You have found the secret page!</h1>

export default withAuth(SecretPage, "You must be logged in to view this page");

In this code example, we're once again using the withAuth function to wrap our SecretPage component. But this time, we're passing in a second argument that is a string message. This message will be displayed to the user if they are redirected.

So if a user tries to access the SecretPage component without being logged in, they will see the message "You must be logged in to view this page" before being redirected.

Customizing the redirect message is a small tweak, but it can go a long way in improving the user experience. By providing users with a clear explanation of why they can't access a page, you're helping them understand the purpose and value of logging in. This can ultimately result in more engaged and satisfied users.

As Winston Churchill once said, "However beautiful the strategy, you should occasionally look at the results." And when it comes to user experience, the results can speak for themselves. Instead of just blindly following the common notion that productivity is about doing more, consider doing less by prioritizing user experience and removing unnecessary barriers.

Code Example #3: Redirect with Automatic Timeout

Are you tired of manually redirecting users who aren't logged in? With Next.js, you can create an automatic timeout that will redirect users after a certain amount of time.

First, you'll need to import the useRouter hook from the next/router module:

import { useRouter } from 'next/router'

Then, you can create a function that will redirect the user to the login page after 10 seconds:

const redirectWithTimeout = () => {
  const router = useRouter()

  setTimeout(() => {
  }, 10000)

Now, call the function when the user visits a protected page:

const ProtectedPage = () => {
  const isLoggedIn = true // replace with your authentication logic

  if (!isLoggedIn) {

  return (
    // your protected page content

This way, if the user isn't logged in, they'll be automatically redirected without you having to do anything. Plus, the automatic timeout ensures that the redirect won't happen too quickly, giving the user a chance to log in if they had simply forgotten.

As the famous philosopher Henry David Thoreau once said, "It is not enough to be busy. So are the ants. The question is: What are we busy about?" Don't waste your time manually redirecting users – let Next.js handle it for you with an automatic timeout.


In , unlocking the power of Next.js is all about making your users feel comfortable and creating a seamless experience for them. With the right tools and techniques, redirecting users who aren't logged in can be a breeze. By following the easy-to-follow code examples laid out in this article, you can ensure that your users will always be directed to the right place at the right time.

But beyond simply mastering the technical aspects of web development, it's important to remember that productivity isn't just about doing more. In fact, sometimes doing less can be a more effective approach. As writer Tim Ferriss puts it, "Focus on being productive instead of busy." By removing unnecessary tasks from your to-do list and simplifying your workload, you can free up valuable time and energy to focus on the tasks that really matter.

So as you unlock the power of Next.js, remember to also consider what you can do to streamline your own workflow and improve your productivity. With the right mindset and tools at your disposal, you can truly achieve great things.
