What game used to be there and what game is there now ? Different styles of games require different play styles many times.
Lots of great advice above. on fast machines try to slow the ball down with dead bounces and cradling, breathing and thinking about your shot. when making your shots successfully that is what your working on.
If you miss your shot then your working on your recovery skills
If the ball is heading toward an out-lane work on your nudging skills. you can transfer energy to the ball better if you nudge at the same time the ball is in contact with something solid
If you are getting frustrated trying to make a shot , cradle, breath shoot something you can hit to rebuild your confidence
When you DO hit your shots, celebrate them (some people shout , some dance, others clap their hands together, even other do them all )
Keep flipping !!!
