To get better at something requires you to admit you know nothing.
If I want to get better at playing the piano, I must first admit what I do not know.
When you decide you want to get better at doing anything, first take stock of what you know, don't know, and what you don't know that you don't know.
Then pick one thing to learn, practice it relentlessly, and master it.
Pick enough things to master, and you'll soon be playing in no time.
But you have to pick a place to start.
