1. Start up a restaurant. My wife wants one. Budget... it depends. If I would buy the location, it could go very high. I don't think I'd be buying as IMO there's a real estate bubble where a live.
So, $150000.
2. Put something aside (really safe bank account, yield not important), just in case things go bad, I go nuts and spend everything else etc. Say $100000.
3. Buy an online property, or more. Relatively big forums with high return potential would be quite high on the list. Other investments. The budget could vary, but say $400000.
4. Help the parents live a more relaxed life: 2x$50000.
5. $100000 to help my brother with mortgage, but he may spend them anyway he decides to.
6. $150000 travel and otherwise have fun.
There would of course be other miscellaneous stuff, but no high amounts worth to mention, but they might take a bit from the other budgets.
