Heaters and Coolers

For the last few weeks I've been bouncing back and forth between very hot and very cold. I catch every flop win every race and then it turns on a dime and goes the other way. I was trying to think if it was something in the way I was playing or just bad luck. Does anyone else find that slight changes in their game happen when the cards run, cuasing a serious downturn. I dont think i've become overly aggressive when its running well, but self analysis is hard. Any input would be greatly appreciated.

Good luck on and off everyone
