What is your goal? If you want to earn significantly more than (let's say) $20,000 a year then poker is probably not your best bet. I used to play during 2007-2010 and the game were getting progressively tougher (more regulars, less fish), the same way as they had been in the prior few years before I started playing online. I recently checked how things are going and the trend seems to still be in place. Additionally, the segregation of countries in online poker (americans not being able to play with non-americans for example) is making things worse and this is in fact what drove me away mid-2010.
TL;DR You are several years too late to have a decent chance of making good money with poker.
Thank you for the heads up. I'll keep it to more causal play. Do you have any experience to with brick and mortar poker? And what are you doing now if you are no longer (presumably) playing professionally?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
