I know many people love to talk about discipline. Discipline is what helps you organize your gambling, and it certainly has its positive aspects. But I see that the importance of discipline is almost always exaggerated. I often read that a gambler lacked discipline to win. Or that they could have been a long-term winner if they had maintained discipline, which is difficult. People often associate discipline with self-abuse.
But discipline is simply following the rules. Sometimes you have to force yourself to follow the rules (which you subconsciously dislike and don't want to adhere to); sometimes you often follow the rules out of habit, without any self-abuse, simply because you deeply believe in their effectiveness.
But!!! Discipline says nothing about the wisdom and effectiveness of the rules it is intended to enforce. It may well turn out, over time, that the rules you followed were wrong and led to your losses. Therefore, I would recommend not to exaggerate the importance of discipline.
But as a gambler, discipline is meant to help you have full control over your gambling lifestyle, make you know when to stop loses and probably take profits while gambling, as a way to avoid further loses. And as such, discipline is very important, despite the fact that some people exaggerate it. While secondly, for the fact that you are disciplined, doesn't stop you from exploring other methods which you believe can help you in your gambling journey inasmuch as it's still within the amount you can afford losing.
