Don’t shy away from your perceived or actual trouble spots of your game. It’s often hard to admit to our trouble spots/shots. Try to avoid thinking of them as a weakness. Too negative.
If you’re truly trying to reach a “higher” level, make a list of your trouble spots. Then narrow them down to 2. Take these to your respective coach and get to work. You do not have to make these “spots” a weapon. Get them to a point you have a decent level of confidence.
Presumably you have strengths and weapons you can and will always rely on. However, too often we spend much of the time avoiding the things we don’t have confidence in to the detriment of our best parts. That approach may be due to ego, insecurity, not being aware, or constant “must win” match play.
Assess, admit then achieve.
