Don't do it. Go to college while you can, and while you are still in "study mode". It is desperately hard to get back into that after being away from it for a few years. (If you really are weary of study, then take a semester or two off---but get back into it!)

I think you'll learn who you are outside of high school just as well in college. Once you have your first degree, you will also have a richer understanding of the world--some through study and some through meeting the college students from other places. When you do finally travel, assuming you have monies for all of this, you will have a deeper appreciation of where you go and what you see and who you meet. IMO
