2) Girlfriend. (Surprised this hasn't been mentioned yet.
3) Get a patent. (More for myself than for profit. I need to know my ideas aren't all junk.)
4) Get an album released. (My first one, of course, will be poorly recorded and free!)
5) Drink more on holidays.
More ideas for the future:
1) Buy a large countryside property. (About 15-30 minutes from my house are plenty, this eliminates the need to drive far to places and is good protection against zombies.
2) Install rather efficient solar panels (25%+) or wind generators on my property. (Right now solar energy sold to the grid is worth 4.5x as much than wind...so...)
3) Collect enough money to do #1 and #2.
4) Collect enough money to do fun expensive things I'm not able to do now. Like restore a classic car from scratch. Or restore a classic car from scratch and install a hydrogen fuel cell hybrid engine or something wonky like that.
