most of the pints that you have listed are very valid, but i feel that there is meeting that is missing which is greed, or is greed not also a bad habit that usually cost gamblers a whole lot in gambling?
Greed is something that you should avoid in any matter, not just in gambling because if you have greed, you want to get anything which is not always you can reach. You need to realize yourself so you can think that not all you want can be available at that time. In gambling, when greed posses you, you will lose all the money because you need to spend money before you can get another win money. That will be a bad habit for the gamblers because he will not think that money is essential to his life.
