$750k Dissapointing and Unmotavating

OK, I admit I did horrible in the $750k, I could have done a lot better but making past the first break isnt to bad, i guess better than the first 20 minutes. Anyways, I was killed by 10 10 twice(My hole cards) against JJ and KK. I pretty much got frustrated after losing to JJ and played horribly against KK when I knew I was beat but thought I was calling a bluff. I almost let this bring me down and not want to play since i left such a big opportunity pass me by. But I see it now as experience and one day again I willl be in it or something bigger...
