Think of it this way, Even you said its like going from high school to collage. If you don't study in high school, you get poor grades and goof around all 4 years, The chances of you getting accepted to collage, or if mommy and daddy give you a full ride paying your way in, doing good in collage are slim to none. If you study and work hard in high school and do get the good grades, Your more likely to be successful in collage. The same goes for poker. If you don't study the game in low stakes, the chances of you making it to the "pros" is slim to none. And as with collage, Say mommy and daddy buy you a $5,000 seat at the
wsop or WPT, and you didn't study poker, you will not be successful in the higher levels. I hope this helps.
