I certainly wouldn't work for anyone else again, that's for sure.
First I would set myself up with a nice house and a few small businesses for creating residual income.
I would take the extra free time I have to learn the programming languages needed to creat Iphone Applications and I would get to work putting my ideas out there for the masses to download.
Just charging one dollar per download for a really entertaining and addictive puzzle game would generate more income and I would slowly build my financial empire on creativity.
I would devote myself to my writing and art projects. Charity wouldn't come in the form of money, but in the form of community service. IE, mentoring, devoting my time to working with kids like I wanted to do when I was in high school, etc.
