Mad Genius,
I've learned the lesson you just went through already. Last year, when I wasnt such a good player...Profitable but not much else....I jumped on a 10/20 limit table after losing to some horrifying beats. I left down a grand.
I think true poker players have all been through this at one time or another (espcially online players). Jump to the higher limit while on tilt. ugh..why do we do it??!! Anyway, I know it sucks, but think of it this way...you will never do that again. You will rebuild and command money again. It will never be thrown away so haphazardly into the eagerly awaiting players at 3/6 or whatever limit it may be. The more expereince we get, the better we can control our emotions and our bankrolls.
Today I lost a $350 pot with trip 4's to a runner runner full house...all-in on the flop on a $100NL table. That has been my poker life for the last week and a half. And it's a safe bet that I have been very unhappy (understatement) with all of these tough, tough beats. But I know I will get through this difficult time and be better for it. You will do the same.
Let us know when you start kicking some ass again...and good luck!
btw.. I just completely forgot to post my bankroll report for last week. Probably because it was so bad. I've been trying to forget this past week for a while now

I'll post it tommorow but I'm gonna go hit the sack for now. later!
