Most of the gamblers doesn't really care much about their previous loss, when they decides to play again or deposit again they would just focus on their current deposit if it would be consider as a lose or win.
Only few would list down or record all of their gambling activity to monitor if they are winning or losing.
It's actually much better if you don't really care about your last losses because you definitely get to be more relaxed as you are trying to get the a new predictions on the game but when you are focused on the past losses such that you have got a comprehensive record of them all, it may become a problem to you because you are very likely to become emotional about it when you are seeing that it's not balancing up in that your losses appears to be much more than your profits but if on the contrary your profit is more than your losses, you could actually get too excited and that too may Also have a way of affecting your phycology and how you play your games too aswell.
So either ways just try to maintain a balance in between that way you will be able to get the kind of results you have desired gambling, focusing on your current deposit and seeing how well to grow it is most important because it will be the one from which you can build up unto recovery if you really care about recovery.
