It sounds like you are already doing it! Fixing annoying stuff as it comes up feels painful and tedious, but that's the good instruction you'll remember. Hopefully you aren't hitting too many work stoppage type issues. Definitely reach out for help for those, but be prepared for uptight people to tell you "RtFm noOB". You'll get it done.

My only advice is to give a little bit of time to learning at least basic bash commands (search and print a cheat sheet) and basic Vi / Vim. Vim is what got me to Linux in the first place to be honest. Those 2 things will give you the latitude to move around and work on any issue you might come across as any user even if you "break" something.

Good luck! You're already doing the hard stuff.
