Just read through all the posts again and it seems (and I apologise if this is way off the mark) that you only find enjoyment going for that 'big win'. Your post describes how pissed off you are at getting outdraws and doing your bankroll every week. Maybe winning money, rather than losing it is the root cause of your discontent.
If this is the case than it much better to 'only' win 10-20 pound in a small buyin MTT then lose 10-25 pound in a bigger buyin.
As others have already repeated here, your buyin in relation to your bankroll is causing the problem. I can only guess that you will either stay unhappy losing money, or be bored winning money in the small buy ins.
As also previously stated, you need to keep records. Even if you do have a big win you will prob still be behind due to reloading your account every week.
Sorry this all sounds so negative, just trying to pick out points from the situation as i see it.
you are very true, poker is all about the big win that i want to hit one day and not about the slow grinding out of £5 or £10 here and there.
Im really here to hit that big on.....one day!
Ok, good luck with the hunting for the big win, keep us informed of how it goes
unless you see me on the big screen...youll no i havent hit it yet lol
