Become proficient in CBT for yourself, especially the part that deals with cognitive distortions - even if you're not depressed. I have now internalized things like all of nothing thinking, mental filters, personalization, etc that whenever my mind tries to pull a fast one on me I'm able to quickly rationalize the negative thought by seeing the cognitive distortions in it. But like everything this requires a lot of practice to do mentally (I nearly did it for 1 year with pen and paper first - actually I made a web app for myself to do it but you have to write it down in the beginning)
