It takes over all of your free time.
Anything you want to get particularly good at will.
Even when you're on a team, you're still on your own.
Yup, it's not like some other team sports.
It's a very alpha-oriented sport
Sometimes it's an a** oriented sport too!
It can be extremely expensive.
It doesn't have to be but people shouldn't buy $2,000 cues when they can't make three balls in a row!
You are always going to need a bigger room if you want to play at home.
I have been to some excellent players homes who had a good table (one was a Gold Crown) pushed up to the wall on one side just so they could have one at home at all.
Pets & Pool are usually a bad idea.
Training your pet to stay off the table would help. Some shed some don't.
Everyone thinks they should teach you.
Many just want to help. There is a LOT to learn!! You can pick up bits and pieces or ideas from almost anyone.
The better you get, the more your non-playing friends will look down on you for it.
Your job is to separate the wheat from the chaff. The players from the contributors. They should be learning stuff from you.
You will never be able to pay the bills with it.
Seems from what I have observed over a great many years is that a lot (not hardly all) of money players are just passing the money around over and over.
You will stay awake nights thinking about a single shot you missed instead of enjoying the other 99 you made.
It's the ones you miss that will kill you in a game. I have two shots in particular that have haunted me since about 1985! It keeps them from ever happening again!!
