I played On-line for years before I went to a Live game and yes it is very hard to transition into Live games, but once you realise that everyone there is in the same boat as you, just at a different stage in their Poker career, it becomes easier.
Try making rules for yourself, like my favourite rule number 1. If you ain't had to pay, you don't have to play. Meaning if you have not posted a blind there is no reason to get involved.
Now I am not saying you should fold every hand until you post a Blind, but you have to have a good reason to call or raise if you have not already invested in the pot.
Yes sometimes you fold 7/10 before the Flop and it turns out you folded the winning hand, when the River would have given you a straight, it happens, but are you really going to fish with every possible combination of any two cards?
Poker is a game of Patience, and it takes time to adapt to live events, but I would certainly rather play them, than clicking a mouse button.
The only bit of advice I can give is be patient, stay focused on a basic
bankroll Management Strategy, and you will not go too far wrong. Don't think for one minute that because you win one Free-roll MTT that you can go and crush in a Live game because it rarely happens.
I find the Social Interaction between players in Live events much more rewarding, and I enjoy the atmosphere in a Casino as much as the game itself.
