Force your brain not to make stupid moves that could compromise your economy.
It's true, it used to happen to me a lot before, because of the adrenaline of the activity or something, I felt like I couldn't do the bets well, I don't know, it was something strange, it was like I was calm but I was making clumsy movements and that made me make mistakes and consequently lose money, sometimes that happens, then I realized that this is a consequence of the emotions, I learned to control it because losing money because of that was not fair.
