If you want to evolve in poker, you need to study the game thoroughly.
And the big lie is that you only need to invest 4 hours of your day to make a living from poker.
Is that you? What do you tell me?
Lie: You can study the poker - i mean, you become profitable - only read, watch & follow the mainstream poker 'education' stuff out there. Personally, I think, it is the biggest lie in poker, but many believe it. This generates a big percentage of new players and fishes. And at the very beginning for a short period, i believed it, too.
Truth: The above is a lie.
Anyway, 4 hours easily can be enough, i know personally guys, whose play only 4-8 hours on the weekends and make a living from poker. Of course, they are low/medium level cg players. For tourney, sng players on that level, obviously it is not possible. (talking about online, i have just ideas about live, probably live it is not enough time even in cg, under medium level.)
