Every tournament you play should feel like a play chip tournament. If it doesn't, and if you feel anxiety or nervousness, then you're playing at too high of a level for your personality and your bankroll in my humble opinion. You cannot win at this difficult game if you are making decisions based upon money issuesrather than upon card strategy itself. Money can never enter the equation, and if it does, if you feel any sort of emotion over money, then you're only hurting your game and your potential success at it.
