More questions to always be asking:

1) How often am I limping in or COLD CALLING A RAISE w/ a marginal hand for no particular reason?

2) Do I understand that every poker tournament presents me with the same competing goals of survival & chip accumulation? Do I play accordingly?

3) Do I understand gap theory and it's role in the way I treat calling someone's AI/ big raise?

If not, do some homework before losing what's left.
