If things, any things, 'p1ss you off', stop now, give up. It's the worst thing you can do. Even a genius market reader who gets p1ssed off will lose.
You had a load of great advice before, enough things to keep you busy for months, but you're back in a couple of days! I think you just have an over inflated sense of your own abilities and expect to do this without putting in the 100s or 1000s of hours. Not just 100s of hours playing at it and clicking all over the place, I mean 100s of hours really focussed study, noting and understanding.
What about your stats? Do you know which race types, price ranges, market profiles are working best/worse ? Are your odds-on trades better than your 6+ trades? I'm guessing you don't keep detailed stats, in fact I'd put money on it.
