Do what I did. Instead of just watching videos, I made notes as I watched them. I looked for consistencies, certain reactions, movement styles, overall play style, etc. You being to see what is working for people, and ultimately, hope to understand WHY it is working. That is the goal, to know why things work the way they do, not just the how part.
People tend to rely too much on tech skill. However, strong spacing with good tech skill is usually enough to break into competitive play. After that you need to force yourself into good habits, develop a consistent style of play, and remain unpredictable. If you ever need some advice, PM me, or anyone else for that matter.
