That’s how it used to be. You asked questions to people who were believed to be wise, and then their answer was what the truth was. And most of the things we “knew” were just wrong.
I agree with what other people have said about using the command line more and the gui less, that will make you have to learn about utils like find, grep, sed, and maybe awk.
Try learning vim (or emacs). Use some command like tools for stuff you’d do in the gui. Try some basic scripting for common tasks. Maybe write some short python/ruby scripts if you need them. I’ve found that writing code has given me a need for learning more about how the command line works, and other “power user” features.
