I think you are on the right track with the self-realization that you're engaged in. You can't develop your game if you can't be honest about your weaknesses, and I think you're starting to do that.
One of the best moves to learn is the fold. Sounds like you have a hard time doing that. Don't worry about being bluffed out. That happens and will happen to you no matter how good you get. But a common mistake beginners make is to under-estimate the opponent or to think your opponent is bluffing all the time. Truth is when an opponent represents a hand, they usually have it. Also, if you are re-raised, you are usually beat. If you get re-raised, then find a good reason to call or raise back - I mean a reason that goes beyond your ego or your disbelief.
Get the book "Zen and the Art of Poker" and develop the poker mindset. Learn to play your cards as they are (which usually means not playing them) rather than what you wish them to be.
Work on discipline and a peaceful mind. Forget the loose aggressive mode for now. Play tight aggressive. Since I've become a winning player, I'd have to say that poker is less "exciting" but more profitable. You often sit on the same chip stack for a long time before a playable hand comes along. Think of your hands as investments. How smart is it to invest in this particular hand?
The fifty posts is easy and should be the least of your worries. Go to the "Learning poker" subforum and ask questions and discuss things.
Eventually you'll want to learn to calculate odds
and eV, but the important thing now is mindset and discipline.
Don't play play money games. You learn bad habits. Hand selection is haphazard and there is no discipline. Play for real money, even if it's the penny tables on Pokerstars
. Don't freeroll too much. Crazy play there, too. I think it's better to learn at ring games, where the value of a hand stands alone. Tournament strategy is a whole other overlay. By concentrating on tourneys, you are learning the game backwards.
