Do you ever feel like there just aren't enough hours in the day to get everything done? It seems like everywhere you turn, someone is preaching about the importance of being more productive and doing more. But what if I told you that doing less could actually make you more productive?

As the great Bruce Lee once said, "It's not the daily increase but daily decrease. Hack away at the unessential." This quote perfectly sums up the idea that the key to productivity isn't doing more, it's doing less. Instead of constantly adding tasks to our to-do list, we should be focusing on removing unnecessary tasks that drain our time and energy.

This may sound counterintuitive at first, but think about it: how many times have you spent hours on a task that ultimately didn't make a difference in achieving your goals? By focusing on the essential tasks and cutting out the fluff, we can actually accomplish more in less time.

So, the next time you find yourself overwhelmed with your to-do list, take a step back and ask yourself: which tasks are essential to achieving my goals, and which ones can I cut out? Remember, productivity isn't about doing more, it's about doing less and doing it better.

Prerequisites for Installation

Before diving into the installation process, it's important to ensure that your system meets the necessary prerequisites. While many guides may simply provide a list of software and dependencies, we challenge the idea that excessive preparation is necessary for success. As Bruce Lee once said, "It's not the daily increase but daily decrease. Hack away at the unessential." In other words, rather than adding more tasks to our list of prerequisites, we should focus on removing any unnecessary steps.

With that in mind, there are really only two prerequisites that you need to worry about when installing the EPEL repository on CentOS 7: a working internet connection and root access on your server. That's it. No need to spend hours poring over documentation or installing additional software. Keep it simple and stick to the essentials. As Leonardo da Vinci famously said, "Simplicity is the ultimate sophistication."

By embracing this minimalist approach, you can save time and increase efficiency. Focus on what's truly essential and eliminate everything else. This way, you'll be able to streamline your workflow and achieve your goals with greater ease. So, before embarking upon any installation process, ask yourself: what's really necessary? And remember the words of Antoine de Saint-Exupery: "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."

Step 1: Enabling EPEL Repository

Ah, the trusty EPEL repository. Whether you're a seasoned Linux veteran or a newbie tapping into the open-source world, you've probably heard of the EPEL repository. But what does it really do? And why do we need it on CentOS 7?

First off, let's clarify what EPEL stands for – Extra Packages for Enterprise Linux. As the name suggests, it contains a collection of additional software packages that are not available in the standard CentOS 7 repositories. This means you get access to more tools, applications, and libraries that can help you customize and optimize your system.

Enabling the EPEL repository is a simple process, and it starts with downloading the EPEL release package:


Once you have the package, you can install it using the yum package manager:

sudo yum install epel-release-latest-7.noarch.rpm

And that's it! You now have access to the EPEL repository and all the goodies it has to offer.

But wait – why stop there? Why not explore other repositories and add even more tools to your arsenal? As Bruce Lee once said, "It's not the daily increase but daily decrease. Hack away at the unessential."

In other words, perhaps productivity is not about adding more tasks and tools to our to-do list. Perhaps it's about identifying what's truly essential and cutting out the noise. So go ahead, enable the EPEL repository, but don't stop there. Take a moment to evaluate your productivity approach and see if there are any unnecessary tasks or tools you can eliminate. Who knows, it might just be the key to unlocking your true potential.

Step 2: Installing EPEL Repository on CentOS 7

Installing EPEL repository on CentOS 7 is supposed to be a straightforward process, but many users hit a roadblock right from the get-go. They find themselves trapped in the maze of installation commands, unsure how to proceed. The thing is, most installation guides out there tell you what to do, but not why you're doing it. I want to change that.

Let's ignore the technical details for a moment and talk about why you need to install EPEL repository in the first place. If you're not familiar, EPEL stands for Extra Packages for Enterprise Linux. These packages are community-driven and not included in the standard CentOS repositories. They offer additional software that may be useful for your projects, such as monitoring tools, web servers, and programming languages.

So, why bother with EPEL when you have the standard repositories already? Well, as the saying goes, "The more tools you have, the more problems you can solve." EPEL can give you a wider selection of packages to work with, which in turn can make your life easier as a sysadmin or developer. You don't want to limit yourself to what's available in the standard repos when a better solution might be available in EPEL.

Now, let's move on to the installation process. The most common method is to use the "yum" package manager. First, make sure your system is up to date with the latest updates and security patches. Then, run this command:

sudo yum install epel-release

That's it. EPEL should now be installed on your system. To verify, run:

sudo yum repolist | grep epel

You should see a list of packages available in the EPEL repository. If you encounter any issues, double-check that your system is compatible with EPEL and that you're running the latest version of CentOS 7.

The point I want to make here is that installation guides shouldn't just give you a list of commands to follow. You should understand why you're doing each step and how it fits into the bigger picture. Only then can you troubleshoot effectively and make informed decisions about your system's configuration.

Step 3: Verifying EPEL Repository Installation

So, you've followed our step-by-step guide and installed the EPEL repository on CentOS 7. Congratulations! But before you pat yourself on the back and move on to the next task, let's take a moment to verify that the installation was successful.

You might be thinking, "why bother verifying if everything seems to be working fine?" Well, my dear reader, you never know when something might go wrong. As the great Benjamin Franklin once said, "an ounce of prevention is worth a pound of cure."

To verify the installation, simply run the following command:

yum repolist epel

This command will list all the available packages in the EPEL repository. If everything is working as it should, the output should look something like this:

repo id                                   repo name                                             status
epel/x86_64                               Extra Packages for Enterprise Linux 7 - x86_64        13,722
repolist: 13,722

If you see a list of packages and the "repolist" at the bottom shows a number greater than 0, then congratulations, the installation was successful!

But if for some reason the EPEL repository is not listed, don't panic just yet. It could be a simple issue like a typo in the configuration file or a connectivity issue. Try double-checking your steps and verifying that you have internet connection. If all else fails, you can always seek out help from the CentOS community or consult the official documentation.

In conclusion, verifying the installation of the EPEL repository might seem like an unnecessary step, but it could save you a lot of time and headache in the future. As the great Bruce Lee once said, "it's not the daily increase but daily decrease. Hack away at the unessential." So, take a moment to hack away at the unnecessary and verify that everything is working smoothly. You'll thank yourself later.

Step 4: Updating EPEL Repository

Now that you have installed EPEL repository on your CentOS 7 system, it's time to update it. But wait, do you actually need to do that?

In our modern culture, we have come to believe that more is always better. In the realm of productivity, this means we are constantly striving to do more and more, to accomplish more tasks in less time. But what if we challenged this notion?

As the legendary Bruce Lee once said, "It's not the daily increase but daily decrease. Hack away at the unessential." In other words, it's not about doing more tasks, but about doing the right tasks.

So, before you rush to update your EPEL repository, take a moment to consider whether it's really necessary. Will updating the repository actually help you accomplish your goals, or is it just another unnecessary task on your to-do list?

Of course, if updating the repository is necessary for the specific task you are trying to accomplish, then go ahead and do it. But if it's not essential, consider skipping it and focusing your energy on more important tasks.

Remember, productivity isn't about doing more, it's about doing the right things. So, don't be afraid to challenge the status quo and remove unnecessary tasks from your list. As Leonardo da Vinci once said, "Simplicity is the ultimate sophistication."


In , increasing productivity doesn't always mean doing more. In fact, doing less can often lead to more effective results. By removing non-essential tasks and focusing on the most important priorities, individuals and teams can achieve greater success in a shorter amount of time.

As Tim Ferriss, author of "The 4-Hour Work Week", famously said, "Being busy is a form of laziness – lazy thinking and indiscriminate action.” Instead, we should focus on the tasks that truly matter and dedicate our time and energy to completing them well.

So, the next time you feel overwhelmed with your to-do list, take a step back and evaluate which tasks are truly necessary and which are just busy work. By concentrating on the essentials and simplifying your workload, you can increase your productivity and achieve your goals more efficiently.

Are you tired of feeling overwhelmed by your to-do list? Are you constantly adding more tasks without taking any away? It's time to rethink your approach to productivity.

Contrary to popular belief, doing less can often be more effective than doing more. As author Greg McKeown says, "the essence of productivity is not doing more things faster; it's doing the right things deliberately."

So, what does this mean for your to-do list? It means taking a critical look at each task and asking yourself: does this really need to be done? Can it be delegated or eliminated altogether?

By removing unnecessary tasks, you can focus your energy on the most important and impactful ones. As Leonardo da Vinci famously said, "simplicity is the ultimate sophistication."

Incorporating this approach into your daily life requires a shift in mindset. Instead of valuing busyness, value effectiveness. Instead of constantly adding tasks, evaluate what needs to be done and prioritize accordingly.

To sum it up, productivity is not all about doing more. It's about doing the right things. So, take a step back, reevaluate your to-do list, and see how doing less can actually help you achieve more.
