At first, I read your list and thought, "uh, good luck with that." Each of those take an incredible amount of investment; the number of Grammy winners who write bestsellers, break olympic records, fly planes, and are expert engineers is... zero, as far as I know.

But then I realized you don't have to achieve any of those to achieve a lot. If you try for #1 and fail, you've still made amazing music. If you try for #2 and fail, you're still keeping yourself in excellent physical shape. Try for #6 and fail, and you've still experienced some of the cultural richness of our world.

You might never achieve a single item on this list—but you'd be looking at a very fulfilling life in the pursuit of it.
