When I played Poker for money, it was NOT really funny ... because I sucked at it, without fully realizing my weaknesses. I could be the richest man of the world, but losing real cash over my mistakes and dumb play would still feel agonizing for me.
Nowadays with play money chips I feel as if I found peace with the game. Losing this or that tournament still hurts, but the 'fun factor' still outweighs all the negativity.
