Keeping track of your gambling money may give you advantage to have a close look at your profit & loss and play gambling with care but at the same time if takes away the fun of gambling from you. You will be more concern about your financial gain or loss and will not be able to enjoy the gambling.
But don't forget that we might feel sad or regret if we see the loss that we already got, and that can make us think to recover the loss. I think the profit and the loss will be different, and it could be bigger the loss than the profit so our mind will want to get the loss back by playing other gambling games. But we can hold ourselves from recovering the loss because we don't want to lose more money in gambling.
Perhaps, only a few gamblers who have to track their gambling money by creating a file contain a report of profit and loss from time to time so they can see the details of their gambling time from that report. As long as we can prevent the bad thing that might come to us, then it is okay to have a track of your gambling money.
That's why some people are going to Las Vegas once in two-three years or so, to put all their worries aside and to gamble away a few hundred bucks, keeping no track, no anything. And that's fine. What is not fine is living like that all the time. Some rich folks engage themselves in this harmful way of living, and they can't stop until they hit the very bottom. Do I envy them? Hell no!
Can you please tell us what kind of effects do you experience since the day you started tracking your gambling data vs the days that you just keep playing and not recording your data. I am happy to hear a personal experience from other users here since I don't track my gambling data cause it's a hassle for me and I think it's not justifiable for me to record my own gambling data.
