Nice reminder of what sometimes seems obvious but always good to read posts that refresh our intuitive thoughts regarding exercise and "diet" (which I prefer using the word lifestyle for instead) as a diet implies periodic eating habit changes, which in my opinion do not work.
It has to become your lifestyle for it to continue to be a part of who you are and therefore becomes habitual instead of periodic, or sporadic. :-)
great post.
