My thoughts exactly but...here's a little personal experience.
My left wrist action is a component that I've ignored as I've focused on mastering others. It dawned on me a few months ago, "I have a hitters left wrist action and I'm a swinger! I have turn and roll, but not enough.
That's a component I'm working on now.
Only a few components to go and I'll finally have a swing that's all mine!
