I'm talking about diligence with motivation. You need to use your body, and your brain, in practice. I would review my notes on other players' styles before I played them. I've always treated each match very seriously, and I don't make the same mistake twice. Definitely no shortcuts.
Table tennis requires a lot of practice.
It's not a sport that you can simply rely on power and speed to win. You need a lot of control, strategies and skillful touches, too. First of all, you need to spend a lot of time practicing. As I said, there is no shortcut. Secondly, you should never give up.
