Said "one more to break even" like 4 times yesterday before I actually stopped

First loss happens, fine, that's trading, told myself one more and I'm done for the day regardless of outcome. 

Lost that one too. Said the same thing again. You'd think I'd learn after round 2 but no. 

By trade 4 I genuinely wasn't even trying to break even anymore, I think I just wanted the sick feeling in my stomach to go away and somehow more trading felt like the answer to that, which makes zero sense typing it out now. 

Break even has never actually been the place I stop, it's always further down than that. What's everyone's actual stopping point and does it hold or does it move too
