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 what's makes us human, it is inside us and we can't deny that.
That is the reason we should be able to control ourselves from being greedy. Obviously, it will really affect our gambling activities since that would usually make our bets at loss but we can be greedy all of the time since as I said, it is inside us. Also, it is not a habit, it is a natural classification of us humans the reason we are gambling.
