My best tip: Create re-occurring calendar events for your exercise times. When a conflict arises, it forces you to consciously choose work over exercise, and often you'll find you have time for both.

Even though my work life is very intense, I make a conscious effort to be healthy.

I try to get seven hours of sleep every night; I always walk or bike to work; I make a point to eat well and take my vitamins; I drink tons of water; and I always spend a portion of my day at a standing desk.

Anything to do with children, sign me up! I work a lot with St. Jude's Children's Hospital, which is an incredible hospital in Memphis that treats children with cancer for no charge whatsoever, including the families' lodging and all of their bills.

My dream is of a place and a time where America will once again be seen as the last best hope of earth.
