Diet and exercise are the hardest things to grow discipline around. It is human nature to be lazy and to consume.
If you can be disciplined and defy these primitive human instincts, then you can discipline yourself anywhere in life.

I tend to agree with this. It appears that the “willpower/ego depletion” study does not replicate, by the way. Anecdotally, in my own life I’ve found the more will I exert in one area the more resolve I have for successfully tackling other tasks and goals. I don’t know if this is the same for everyone, but for the most successful people I’ve observed it appears to be the case.
Just like any muscle, willpower seems to grow stronger when you exercise it. Why we ever thought the opposite (including me) I have no idea.
