The best post I have read for a long time. No joke.
Its about making the decisions which make you happy, and winning £s is not the only thing which makes you happy.
Sort of along those lines at the end of BB10 I got a "tip" that Rodrigo would be going out 5th and the odds were about 4s, through the day I put more and more on it at betfair until I had about £2k profit should it come in. Just before the show started the odds had come in and I realised it is a bit rash to bet that much on a "tip" and it was still around 3s and I bottled it and layed off for no loss or a couple of hundred if he came 5th. He came 5th. I was gutted, really really cross about it. Even though I had made a few hundred £s I honestly would have been happier of he had have not gone 5th. I would have made no money BUT I would have been smug and thought I was such a Pro not taking silly risks and hedging my bets etc etc. I wouldnt mind the £0 profit I would have been very pleased with myself. As it was I made quite a few £s but I was Pissed off about the fact I bottled it when I had £2k at my fingertips.
Thats a bit off on a tangent, but overall the point is I relate to what you are saying it is not just about the money you win or lose. It is also were you happy/upset that you made the decison.
