Ice helped me realize this when he did his EV of all ins preflop experiment many moons ago...
Wasn't that me on the old UPF (or did Ice do one too?)
As for not minding the bad beats I find that a large bankroll and the Tao of Poker book help.
But the best medicine is to win (and thoroughly outplay opponents whilst doing it) - drop down to $25 NL or $5 SnG's - if you are still on tilt your losses will at least be trivial and you know it's time to take a break. If you win you get your confidence back...take my week as a example..
This week I have been playing the Party $25's as part of the Party Challenge (start with $100 on the $25's and see how high you can go). The bad beats I suffered were tremendous, and I went on tilt, to the extent that 4 days in I had lost $113 (I had $12 left thanks only to Eurobet's $25 hands played bonus). I battled my way back up to $50 but still felt pretty lousy...
Then last night I found a true 24 carat gold maniac (91%Vp$iP, 26% PFR) with a huge stack ($130) sitting two seats to my right. His standard raise was $5! (doesn't give you the odds to set or fold small/medium pairs if you have full buy-in). He was running over the table like a truck. He wasn't totally stupid though and would back off on the turnr/river if his bullying didn't pay off.
I took some money of him with a set of QQ but had to give most of it it back when my AA hit an all diamond flop (no diamond ace) and he re-raised my pot-sized bet all-in on the flop (he was probbaly bluffing or on a flush draw but I thought I would find a better spot).
I decided to try to tilt him. I set him up with an all-in river bluff when a flush draw I was chasing missed (a high variance move but I had bet it all the way and was already in for 45% of my stack and put him a draw too). Then I showed it.
He was super-keen to stack me after that but of course I was waiting for a good spot - no more bluffs.
10 minutes later I got AKs and 2 folks called my pre-flop raise (he was one). Flop was rags but 2 diamonds and I checked. MP (with $5 stack) pushes, Bully raises pot-sized, I push all-in. Bully calls. My ace over card hits and I take down nice pot. 'Thank you' I say. He is steaming now and his stack is under $100 for the first time I've been seated there.
I keep waiting. Finally I get 88. He raises to $5 but my stack is $65 now and I have odds to call him and set. And I do

I check. He bets pot. I call. On turn I check, he bets pot, I push my last $20 in , he calls and loses. Result I have $130 stack. He is down to $30 and drops out (notice still in profit for the day).
I won on the other 2 tables I was playing too and took my Challenge roll from $50 to $190 in less than 2 hours...am now $10 away from the $200 I need to move up to $50NL tables.. bring it on man...rock and roll..
