Frankly, I don't see what's so mystifying about this.
There are some people I know who absolutely hate what they do for a living, but they stick with it because the money's too good. Ironically, some of these same people tell me that they plan to retire one day so they can take up custom woodworking as a full time hobby.
If that's true, when the day comes that I chose to retire from my "work" what would be an appropriate hobby for me? Custom woodwork?
As Confucius once said: "Choose a job you love, and you will never have to work a day in your life."
Having said that, I am at "work" this morning making drawings for a couple of cool new furniture commissions that have come my way recently.
Some tunes are also playing, including "Kashmir" by Led Zeppelin.
I'm working on today being another good day.
