When you are at your job long enough, you become a professional at it whether intentionally or not. 8 hours every day wiping asses will make you superior at your craft over the average citizen with the best name brand 3 ply.
After a few years of delivering parcels in the same area, I can confidently say that there are less than a handful of people in this world who could navigate that area better than I. Unfortunately, such knowledge does not land me any great opportunities or beautiful women. I should have dedicated those years instead to weight lifting and the art of lying.
With several hours of spare time and energy, I have the opportunity to become a professional at something. The overwhelming population will only spend 8 hours a day on something if they feel they have to. To do so purely out of your own desire is for the insane and very successful.

With no police, hospitals and rubbing alcohol, death would be my answer to not knowing what to do with my life.
