I agree and clicked to say the same thing, until I read "I'm scared of breaking something" - if you want to get good at Linux, then do what you're scared of, and break things, because that is how you learn.
If you do not want to - which is 100% perfectly fine and acceptable - not everyone has to be a Linux expert and some people do just want to use it - then I wouldn't bother unless there is a specific need.
Take my meaningless upvote!
