My motivation comes from the Lord. My favorite verse is, 'Whatever you do, work at it with all your heart, as working for the Lord, not for men ...' (Colossians 3:23). As long as that remains my motivation I can always work hard.
My most memorable moment was seeing a Mercedes Benz trash truck. They had Mercedes Benz' over there for everything -- taxi-drivers -- it was just a normal car over there. That was crazy to me; to see the trash men pull up in a Benz. I never would have expected that.
