Dirty Jobs' Mike Rowe: Works Hard and Smart

We all have dreams as children. Some hope to become rich and famous. Others have aspirations of healing people, fighting fires, or teaching. You want to change the world or at least your little corner of it. At five years old, I wanted to be a garbage man or a cocktail waitress. (I did experience the latter.) Discovery's "Dirty Jobs'" host, Mike Rowe, had a loftier goal. He wanted to be like his grandfather--a man who became a master electrician and carpenter by age 30. Unfortunately, his lack of coordination sent him on a path requiring vocal drills over power drills.

Little did he know that after years of studying music and working in entertainment, his childhood on a farm would provide ideal training for a career that begin at age 40.
