Doing things that I'm no good at

I trapped myself with small positions. I was trading only 1/3 size and then it's so easy to add and losses don't hurt in the start. I had valid reason to stay in the trades between 9 and 10 a.m. but I forget that I will not go so easily out if and when things turn again against me. That's why I always got to get reminded with losses like this that I need to scalp because I'm not good at other things. I'm slow to responding to danger if I'm in the losing trades so long, my judgment get clouded and I make mistake after mistake.
