How do you know when you\’re ready to play professional texas holdem?

I 'VE that the game now sits and gos on fulltilt for 6 months and' the VE has designed my winnings. I 'VE prepared in the money 18 out of 24 times. For professional poker players out there. How did you knew when you were ready for the big time. Please note that the money is not an issue for me. Thank you!
