Gah, that kid always creeps me out.
I challenge the OP to a race around the world. Ready, GO.
80 Days or less?
Anyway, where do you live?
I challenge you to work hard and save your money to spend 6 - 12 months on a walk-about. The Aplichain Trail, the Oregon Trail, across several European countries....
In lieu of this, I suggest an Outward Bound trip
Or,
I challenge you to do something that you don't want to do; step out of your comfort zone (socially, economoically, physically, etc.)
Or
Do 52 hours of volunteer work in one year
