Sewage happens some times you have to fold just to climb the latter in pay scale.
You need poker strategy and bankroll etc. To do the right calls is some times fold the winning hand. Did yesterday 4 times in one tournament to get 2nd place.
To grow your bankroll you have to be conservative most of the time!

But I do not like what I have to do some times to grow it! But the bigger my bankroll the more games in the future.

I don't think folding the winning hand is never a good move.Its OK if you get bluffed and you fold the winning hand,everyone gets bluffed, but If you think you have the best hand than run with it and get as much chips/cash as you can.All you can do is get your money in when you have the best hand if you get drawn out on than thats poker.It sucks but happens to everyone.
Your right Sh*t does happen.
