How Linux Made Me $200,000 a Year
Picking the right operating system, hands-on skills and taking jobs no one else wanted opened all kinds of doors for me! It can do the same for you without breaking the bank.
Linux is the #1 operating system for servers, IOT, machine learning, Artificial Intelligence (AI) and so many other platforms used daily throughout the world today for governments, businesses, ISP (internet service providers), Cellphone companies (e.g.manufacturers and sellers) and countries where proprietary software would handicap their ability to modernize core platforms that serve their citizens on a daily basis globally.
Linux is the basic foundational path that you must learn and become comfortable with to work in all modern technologies in 2025 and beyond. The days of the point and click Windows GUI (graphical user interface) will not save you when it's time to fix a problem or that UI (User Interface) is down and you can't get to anything but the command line.
All servers in a production environment that run Linux workloads will not run a GUI interface due to overhead and also for security reasons to limit the number of threats possible.
However, you should know what tools are used for operating systems in the real world. All Linux distributions are not worth learning if you want to get an actual paycheck. My philosophy over time developed into, "I'm not learning nothing that won't help me pay bills or keep Mommy happy." Period.
Life is short and let me tell you something. You cannot spend your whole life staring at a computer or your family or significant other looking at the back of your head in front of a monitor month after month and year after year. It gets tiring. It really does.
So learn only what matters and what will pay you. If you want to do some stuff for fun or build your own Linux distribution. Have at it. Do your thing. However, I strongly advise to focus on what will pay you money. The rest will follow:
