At least you know what's really happening with your journey in gambling, you'll not wake up one day realizing that you have already spent a lot of money and yet you are not getting anything from it. Tracking your gambling activities makes you aware of the current situation, therefore it will help you to make a timely decision as well, if you've seen you lose a lot already, then maybe that would become a factor to make you realize that you are not doing well in gambling.
