If you want to practice proper gambling budgeting and see that it works effectively, you first have to start from personal budgeting and then you can easily implement it in your gambling.
What's your take on this?
We are not all the same... If you keep that in mind, you will realize that not everyone is capable of the same things. You wrote everything nicely, and I agree that we should take care of ourselves, but for some of us, keeping track doesn't work at all... that's when you give in too much to the moment & pleasure.
My take is always the same:... don't deposit if you are not ready to lose it. Don't gamble if you can't afford the loss. I am not a pessimist, I am just aware of how quickly & easily luck can turn its back.
