Interesting story... Few years ago I stuck a £50 free bet on Man City to win the league (they won), took the winnings (£350) and bet on Hamilton winning the British GP (he did) and Murray to win Wimbeldon (also did), so I took those winnings (£1000) and bet on Germany to win the World Cup (they did). Won close to £3000, but watching that final game was excrutiatingly bad enough

I probably used up all of my luck in that streak, so I vowed to only bet small. At the time I was going through a "this is money I won, so I'll gamble it" mentality.. it all came from the thought that as I started with a free bet that losing the winnings would cost me "nothing", so I'd take a punt. Never again.
