Agreed. This is something I think about a lot. I like consistency and am always trying to reconcile my personal beliefs with each other. It can be quite hard because it leads to questioning other beliefs that may be deeply held. The classic example is logic/reasoning and religion.
A simpler example that I recently went through was that I stopped drinking alcohol. I never had a problem with alcohol and would have beer or wine here and there. But, the evidence keeps mounting that it's literally just putting poison in your body with little benefits. I felt it was inconsistent for me to workout everyday, eat healthy, and then drink alcohol. So I stopped rationalizing and quit.
