Just like learning to play an instrument (I'm learning ukulele), the tip is to go slow, as slow as you need to, and practice, practice, practice. So what I see some people do for practice is to hack a game you love or hack a bunch of them and mash them together. For example, a friend took a game set in old England and changed the setting and character tropes to fit an 80's movie. I played both original and hack, and they're both terrific. Actually I loved the hack so much more because I know 80s more than old England. So tweak a favorite game to fit what you're into, and then play the new game. It'll give you a sense of mechanics and pace, etc.
