There are people who are extremely attached to money and this becomes a problem when playing no limit poker. So it is advisable that you set aside a bankroll for the game and play with the poker money or the chip. Remember one thing that you should separate the poker money from the rest of your money.
While you are playing and if you loose, your thoughts must not roam about thinking that what you have done to the money. If you get distracted you will only loose more and more. Money that you win or loose is just poker money or the chip sets. So be assured that even if you loose money here that should not have any impact on your regular money.
One most important point here is never play scared, that is if you have the fear of loosing the money that you have in front of you, you can never win or play a strong game. You must be willing to put any of the chips that are in front of you whenever it is required. Just concentrate on the game and forget about everything else.
