best way to learn how to edit?

Hi there, I’m start learning final cut pro and editing i’m also want to make some youtube videos, but i have lack of skill in editing so i wanted to ask what is the best way to learn how to edit, expect from doing it constantly (already do). And I’m macbook and pc user i’ve seen many plugins on Premiere pro and After Effects, question is: is there as much plugins in-final cut as in premiere?

P.S. Thank y’all for ya answer i’m really appreciate that
