Risk Aversion. I think this is commonly my biggest mental game leak. I think at times I get too caught up in trying to have winning sessions instead of trying to play my hand the best I possibly can.

Also after a long stretch of winning I start to feel risk aversion creep up because I start thinking a downswing must be right around the corner.

Obviously this is annoying and effects my game negatively. I start to play less hours and feel myself playing my hands tighter/weaker. 

Has anyone had this problem and fixed it? If so how did you do it? Any advice is welcome even if you have never dealt with this issue.
