Let me tell you how I did it. I remember I wanted to start using Linux full-time no BS and have had some exposure to the terminal. I took the opportunity of a new position, I said I had to use Linux for the day-to-day activities and they bought it. So I had to use the terminal/Linux without disrupting any of the necessary activities.

Meanwhile, I read the beginning half of "The Linux Command Line" [1]. I highly recommend it. Looking back, I might have read it until part 2 and skimmed the rest, and read it as I needed it.

Try to do everything through the terminal. File creation, reading, managing stuff, changing wifi, configuring editors, writing files. Try to find the conversion tools with the rest of the "world". Some examples of what I mean are pandoc for md->docx conversion, python pandas for csv -> xlsx. Build small scripts for your tasks. For example, I work in a multilingual company and I have a tool for translation which at first used Google Translate and now uses gpt. At some point in the journey I even had my own custom dwm build. Fun times. Do read about suckless software, a fun philosophy with some genuine principles, and a nice (but not friendly) ecosystem.

So my recommendation is to read something to give you breadth on linux/terminal knowledge so you can navigate around and stick to it as your main driver.

Another book one I recommend is the "Unix and Linux system administration handbook"[2]. It will tell you more about the history and inner workings when compared to the previous one.
