I'm questioning my play a lot lately as well. I feel like I'm being overaggressive and paying off too much. I have 100-200 BB downswings and upswings every few thousands hands. I notice that the players with the best winrates show graphs that don't fluctuate so much. My winrate has been decent, but not one of the best, and I feel like one of my biggest leaks is paying off too much. I'm just trying to find that thin line between extracting value and paying off and generally trying to play smarter, not harder.
