Hoping to get some advice here. With certain things, my mental willpower is strong AF and can not be broken. But it’s usually with physical things. For example, if I say I’m going to not eat for 2 days, I could do it and fight the urges and pain. No problem.

But when it comes to something like trading stocks (which I’m trying to do full time) and I have a certain set of rules....I break them every time. Over and over. I’m so weak emotionally. How can I build up the same mental fortitude with other things that I’m having trouble with?
