Intriguingly, I daydreamed out loud about this at work and immediately got cold water thrown on me in the form of "you have no idea if you'd be good at that, or if you'd like it" type comments. I know. I've definitely seen the dark side of entrepreneurial things too (and am generally not that tempted). At the same time the cold water made me surprisingly angry -- I wanted to run right out and prove the person wrong. It's interesting that I cared so much.

Still... what would you do if you knew you could not fail? Seriously, I think creating/running a good gym would be A-1.
