Either it is a small amount or not if you are destined to lose then you will lose. Even if you calm yourself down or that if you are in a good mood, it doesnt matter at all.
If you are angry and pissed because you lost you can end up losing more and more money and lost money that you can't afford to lose, so actually it does matter.
I do gamble and I know that there is no strategy to it therefore when I gamble, I consider anyhing that i put on the site as my loss therefore Im cool actually if I lose and If I win then that would be much better. I do gamble to win however and I just go with the majority of my bankroll, it is either I win or lose and has nothing to do with mood
Which game do you play? Hm, you are first person i heard who is cool with loosing his money, even when i deposit 1$ and lost it i can't really say i am cool and ok with it.
