Never work again (unless I absolutely wanted to, for pure fun and challenge). Invest half (maybe some in startups?). Buy a sizable, but comfortable, house on top of a remote mountain in Montana or Colorado, and use it as my headquarters as I trek across the world. But, some amount of time into my aimless wandering, I would no doubt get the itch again, and have to start creating something.
