Some statistics will definitely help.
You can have tracking software show how often you're winning/losing with certain hands, assuming it's online play in a room that allows it. But I'd suggest focusing on other stats like:
* VPIP
* PFR
* C-Bet %
You can track these manually if necessary and compare them to good regular players you respect or just ask here what advice people have based on the stats you find.
With that said, I feel like K9o doesn't win very often either
