I learned the difficult way. Skipping classes at high school at 2010 to play and lose my lunch money. Level there was crazy good.
I truly believe today that some of those guys at that age, could already crack NL50-100. One of them plays successfully short stack strategy live regularly at NL200 in a local poker club around my city (casinos are illegal). I'm from Brazil
, so it's a bit different model in college education, but most of these guys are either studying engineering, med school, so they didn't have time to dedicate themselves to poker.
I started to take poker more seriously last year, when I found at law school some home games where I could exploit a lot of loose passive donks loaded with money from law school. Since them I went back to poker books and stuff, trying to find a way of keeping up my partying and traveling routines as I pay college.
