Heh, to some extent, this is what I did. School was easy (low standard of eduction), school life was boring (team sports or nothing), so I found something that interested me. I learned to juggle, amongst other things. Got decent, then learned to perform.
I performed most friday and saturday night in late highschool, assorted gigs I got through contacts or from audience members. Graduated school, worked long enough to build some savings and buy a flight to Europe, and hit the road with a backpack.
I stuck with it on my return for a while, but ended up leaving it for 'normal' career.
