Shall we did into this some? I spent a lot of time considering what success is in hitting. What I see now, most kids are trying to "get off their swing" and that is their measure of success.

"Most kids" probably isn't fair there. A lot of kids. Too many kids. The swing is important. Learning to swing better is important. Defining success will help to keep you pointed in the right direction.

The ultimate success is not making an out.
- Hitting the ball harder helps prevent outs
- Swinging at strikes helps prevent outs
- Hitting with less than 2 strikes helps prevent outs

Situation matters. Each pitch, the situation changes. How many outs, the score, runners on base, the arm your are facing, wind conditions... lots of info to pay attention to. (This is why I love playing golf. Each shot has this kind of data processing and decision making!)

There are also times when you just suck and have to force yourself to do something. Example: Rolling over too much. Sacrifice an at bat (or an entire game) to go oppo, let the ball travel. Overcorrect for a day to help yourself for a week.

When looking at video, are you understanding the context of what that hitter's reality was? What was the score? The count? Were they hurt? Were they locked in?

Before tools like Baseball Savant (shoutout @darenw), I would download files and label them with count and pitch type. It helped me understand why I was seeing the things I was seeing, to give context to variation.

Getting your swing off is good. Especially with less than two strikes. Hitting homers is good. But there is a much bigger, deeper story going on with EVERY SINGLE PITCH of the game.

Understand the success you are seeking and you have a North Star. Everything gets simple from there.
