Here's a 15 ball drill that will actually help your game.
Put the 8 in the center. Put the stripes on one half and the solids on the other.
Run all stripes or solids while staying on that half of the table. Then cross over to the other half and do the same. If you cross over prematurely or hit the 8 ball, start over.
A variation would be the same set up, but alternate between stripes and solids. You are allowed to cross over at any time, but not mandatory. Although the advanced version would have you doing so every shot. Helps in pattern planning and getting on the right side of the ball. Wrong pattern and wrong side makes it tough to cross over.
