When I can't get out of the house, I clean it.
You may think that has nothing to do with pool but it does. If you do productive things to keep your head clear, it will help you stay focused and guilt-free when you do get to the pool room to play. You won't be distracted by thoughts in the back of your head of something you are neglecting by playing pool.
Think.....What can you do at home that needs to get done? Homework, pay bills, clean, go through that stack of mail or papers you've been avoiding....All of that helps your pool game.
