My dad asked me a couple days ago if I knew what the definition of insanity was. Yes, I said, it’s trying the same thing over and over again and expecting different results. So he asked me why I keep trying.
Some things are worth going crazy over.

oh this is crazy! I just read a poem that reminded me of this concept. Take a look: https://youcanstoptryingnow.wordpress.com/2015/04/11/radio/comment-page-1/
I agree, some things are worth going crazy over, love it one of them.
You guessed it
I think every time for yourself it is a little different. You are a little different each time. What works one day, maybe not the next.
One’s insanity is another’s routine
Alternatively, one’s own insanity is one’s own routine.
