I often had emotions that were higher than me and I lost the same way. But I often remember that other players have the same problems and why other players can be better than me in this. Then my competitive spirit awakens and I understand that I will not be worse than other players in this, at least I try to make myself better in this. We should always strive for this, to be better than other players, otherwise why enter the game at all if we are weak in many things, including emotional ones. In general, I think it is impossible to improve your emotionality in any way, except by playing for big money yourself, so that in the future the pressure is not put on us by money, but not everyone can withstand this.
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.
