When you sit down at a poker table, you shouldn't be concerned about money. Those chips in front of your aren't money any more, they are poker chips. If you are concerned about the money on the plays you make, you will never win in the long run.
So when you sit down, don't think 'OMG WTF THERE IS SO MUCH MONEY HERE!', just be comfortable and play your own game, no scardy-cats allowed!
