re: Poker & Bankroll Question
I know playing online poker when you are young seems really cool and you'd love to make a living at it. I am guessing that you live at home and are not married, nor have any kids.
I have a mortgage, car payments, college tuition, dental bills, car repairs / insurance, life insurance, christmas presents, birthdays, driving lessons, proms, weddings, retirement to pay for. It's called life and unless you intend on living at home with your parents until you are 40, and remain single and childless, you will not be able to support yourself through poker.
Go to school, get a good education, get a great job, or better yet, start your own business and work for yourself. Or do what I do, and do both and treat poker as you should, a fun past time.
