I'd invest it until I was 20 years old, most of it or about 900k into stable and profitable stocks, and the other 100k I would spread throughout risky starting ventures in hopes of scoring big. Hopefully I would have around 2-3 million by the time I was 20, from the 900k and more from the 100k, Then I would buy myself a nice piece of land give or take 10-15 acres. Build a house that is roughly 3 stories with one being a basement, and then put everything I can into the house within some reason. So it would have a gym fully fitted, a library, a really nice kitchen (stainless steel everywhere and everything I could need), a wide open floor area for many things with some sort of running track or something, and probably an inside swimming pool. More that I can't think of now, but anything that I didn't use building the house and making sure I had no debt would go back to where it was so that I could just take a bit out when I needed it and live my life doing what I wanted when I wanted.
