Becoming a professional trader

Hi Pat,  I have been trading for over a year now. I am working part-time as a freelancer, usually about 2 to 4 days a week. I would like to become a full-time trader. Therefore I would need a minimum of 20% profit yearly. How realistic is that with your style of trading?  Furthermore do you have any other tips or things to consider when making the move to fulltime trading? I would be glad to hear about your early experiences with that.  And I want to say thank you for your hard and good work here! I am only here for two weeks but can already notice the positive influence on my trading.  Best, Upgapper
