I've pretty much gotten over being tilted by bad beats, except in the most extreme cases. What tilts me the most now is being card dead/cold decked. Sitting there for hours folding 93o watching money flying around at a super juicy table and getting NONE of the action.
Folding 93o for hours and the new guy sits down at the table and gets AA, KK, AK, JJ in their first 30 minutes.
Folding 93o for hours while watching the stack of the absolute worst player at the table grow and grow.
Jealousy tilts me
So I pull out my ipod, read a book, talk a walk, maybe go rail a friend for a while. This is still the tilt i have trouble dealing with the most because live poker is so slow.
