That's what worked for me. Started out walking the dog every morning which gradually turned into a 5 mile run with the dog. I feel for guys that are working 10-12 hour days in high stress positions and have children to top it off. That used to be me and it was tough to make time for your health.
That's me. I'm asked to do 10 hours of work in 7.5 hrs. And then have to explain to my boss I did't get it done because it's not physically possible. The thing is, though, that I wouldn't have it any other way. Caffeine in the day, alprazolam at night. At some point it'll catch up to me. I'm just not wired for it.
