I've been getting up early to run for something like 6 (wow!) years, and, while I am grateful that I do it this way, there are a lot of mornings my brain is screaming "NOOOOOOO!!!!!" like a tired two year old.
I am always glad that I did get up early afterwards because if I didn't kids, work, and the heat would all be my excuses. And I really like that feeling of being up and doing something before anyone else is up. I've never regretted getting up early even once.
Why does my brain have to be so obstinate?
