Training
Without training there is no improvement. Even on a high level it is still important to learn new things and keep working on existing skills. But every training regimen needs to be adjusted to the individual as practicing without a clear goal and a well-designed plan will not bring the desired success.
Exhibition
Do you have any kind of opening or you have a special event planned, how about a pool billiard exhibition from Jasmin Ouschan to entertain your audience.
