When I start trading I try to make myself aware that this is a process but it is complicated because I confuse the results with the process, if I manage to make money I feel like I am a good trader but if I continually lose I think I am a bad trader. Any advice? How do I clear my mind?

Hello everyone, I've days where I'm fully focused and trade after my system. But sometimes I don't know what happens in my brain, I overtrade, I go against my rules, I lose many trades in a row, and it feels like I am another person. After that I realize what I did. There are also days where I'm in profit, but my inner self wants more profit, even then when it's really more than enough. It feels like I can't get enough. I don't know exactly how to deal with it on a long term basis. Do you have some tips? Thanks in advance for your support
