There is a very simple test to see if you should join a pool league.
Rack 10 balls, 1-10 with the eight in the middle, just like you would with a regular 8 ball rack.
Break the balls, don't worry about scratching, just break them up.
After the balls come to rest, grab the cue ball, and place it anywhere you want, and start shooting, start with "Cue ball in hand" only after the break.
Shoot all the balls, in any order except for the Eight, the Eight ball is last. Stop shooting, when you miss, scratch, or pocket the Eight, whether it be and the end of the run or unintentionally during another shot.
Now count all the balls you have pocketed, even ones made on the break.
Do this 9 more times for a total of 10 racks.
After 10 racks if your score is;
0 - You might not have fun in a league
1-100 - You will have fun in a league, go join one!
If it is more than 50, do a AZBilliards search for ways to self rate yourself.
And remember, have fun and leave the worries at home!
I appreciate all the replies. Thank you to everyone for the advice. When I get home tonight I will give this drill a shot and post back with how it goes.
