Hard work and accomplishment are the flagstones of a man’s desire for work. The difficulty lies in what you end up doing to your mind and body. I learned the hard way that a body can only take so much. Working 70 hour weeks as a math teacher in middle school, my body shut down and the chemicals in it broke me down. Where I didn’t have a real problem working those long hours before because I loved working with my kids in the classroom, this time it was stressful.
