Stop looking for tactics and start looking for motivation. I was a heavy drinker suffering from depression and anxiety. My wife left me and started dating a friend that's been trying to get with her for years. Revenge is my motivator, which some people might not like but I'm in the best shape of my life and curbed a lot of bad habits and patterns.

I'm not a self-help type of guy, but the Tony Robbins documentary on Netflix made me start to think about my life as something that can be designed, the same way I would design software.

Fear and anger are much stronger motivators in my opinion than love, fun, or sense of accomplishment. So I'm not afraid to leverage those at least in the short term. Find the person or thing that really pisses you off, even if that is a version of yourself.
