things to remember.
Nobody started out playing pool like a pro-- EVERYONE had to learn how to stand, bridge, hit the cueball, make a ball. There is nothing to be embarrassed about.
A poolroom has different people from regular life. But when you've been to enough of them, you will see that these strange people are almost always the same, poolroom to poolroom.
Almost everybody secretly wants to be either a teacher or a hustler. Sometimes both. Missing balls will make both types look at you to decide whether it's worth the trouble of approaching you. Missing a whole lot of balls will make them decide it's not. : )
Everybody in the poolroom wants something- usually money. If you're not giving away any money, people lose interest fast.
As long as you aren't jumping up and looking around the room after every ball you make and miss, people won't pay much attention to you. That jump up- look around stuff is the poolplayer's mating call for getting a game. If you keep aware of your surroundings but not look around like you want something, people will lose interest fast.
There's no better place than a good poolroom.
Rarely is anything what it first seems.
Be there to see, more than you're there to be seen.
Take it slow and easy.
And you have nothing to be shy or embarrassed about.
