We sometimes do things right, what you say reminds me a lot of what we say: "Insist" and the fact of insisting at least for me has worked a lot and is something that makes me feel proud , but in the game the fact of insisting so much can be dangerous because if we spend our money we will lose capital and it turns out to be worse, then in view of this it is better and a thousand times better to have our plan clear and the best plan is to always have money willing to lose , if we have that clear we can continue trying any activity safely.
It is good that you are telling about the planning of gambling for example if your budget is about 100$ then you may place 10 bet for 10$ is or something like that and if lose then you will stop gambling. But who told you this that you will be able to control your emotion after losing the fund and how you can be sure that you may not reinvest on gambling?
