I see it happen a lot with beginners, they use all efforts to make the ball just land into the table. And the biggest mistake I see is beginners stopping to practice fundamentals when they reach a minimum level needed to execute some shots. That point when they conquered the technique to make a shot but do it without confidence and want to start to apply tactics in a match.

Between points I think of what went wrong the last point, what tactics I should use more often. Like if I looped cross court and they were waiting there, I make sure to remind myself to go down the line. Think about what worked last time, like a deep fast push wide to their forehand. There's actually so many things to think about now that I'm thinking about it. But I think in general you should try and identify one thing to keep in mind between each point. Having some set strategies also help, like serving half long without much spin and attacking the third ball strongly. Serving regular spin (reverse for right handers) to their short forehand, getting into position to loop with the backhand, or if it's reverse spin, getting ready to attack with forehand.

Generally you don't want to be thinking of a specific part of your technique. I think the closest I get to that is reminding myself to loop more against people with heavier pushes, or to attack more against opponent's with generally lighter spin (like short pips pushes).

It's also applies to Table Tennis etc.
