My favorite quote is my own. I was playing at the final table of a $600 buy in PLO8 tournament. I was holding 34JJ not sure what the suits were. Somebody raised, I folded my hand but when I did my hand got flipped over. Someone made some remark like I can't believe you folded that. My response was "If you think I should have called a raise with that hand you're going to have a hard time beating me today."
poker is like stairs, if you don't know how to move forward you fall down and go to ruin, and it is very difficult to get up, you have to learn to be patient.
“The strong point in poker is never to lose your temper, either with those you are playing or, more particularly with the cards. There is no sympathy in poker. Always keep cool. If you lose your head you will lose all your chips.” -- William J. Florence
