On the chance cesar is not just trolling, here's a real answer.
Play for 2 months on play money tables. See if you can beat those players. Then play
freerolls and see if you can get a
bankroll. When you have $100 made through freerolls, move over to micro tables and mini-tourneys and see if you can build your roll there.
Use excellent bankroll management. Never put your whole roll on the table. See if you can avoid going broke at all for a year. Or three.
Read at least 5 top
poker books. SuperSystem, Harrington on holdem (series), look through the book section on others that might help. I like The Poker Mindset a lot, but it's more advanced. Try doing some of the things in these books one at a time. Eventually try each thing. Find out what works for you. Develop your own style of play.
Watch every lesson in the FTP Academy, and every session. Watch them again. Take the tests. When you start playing for
real money, take the challenges. Look around the net for similar help. When you have made $100K, invest in a poker coach. Or a WSOP Academy class.
After you have been playing for two years, see if you are breaking even. Many people can't do that. Most cannot.
If you can go from $0 to $50000, you may be ready to consider going pro. But then you have to take into account whether you can make a profit beyond your basic expenses, which will have to come out of your bankroll monthly. So, if there comes a point when you think you might be able to pull this off (few can), take a two week vacation from your job and play as if it is your work (8 hours each day, with disciplined breaks.). See if you can make more
profit than you would make at your regular job.
Then think about whether you can stand doing that every day. By that point, you will have considerable experience and vast familiarity with variance. You may have a clue whether you are mentally capable of playing poker for a living.
I am, of course, thinking "pro" as someone who makes a respectable income over the course of a year. If you live in your parents' basement, and you make the $200 a week you need for food and stuff grinding away online, and that's what you live on, that could be a "pro" too.
