1. Do something - especially if it is an idea that contain things that You don't know at the moment - by trial and error You will learn things. 2. Find a mentor - this is the fastest way to improve. I have 5+ years of experience in frontend development - lately I've learnt a friend how to work in the frontend development and after one year he know almost everything that I do (I don't want to talk here about dealing with specific quirks and/or development problem solutions by programming because it is something that You'll eventually achieve with time) but yea, I was learning by trial and error and he wasn't wasting so much time like me because I've told him everything before he even tried.
