1. If you piled up that amount by doing unethical work, donate at least 20 percent to some needy organizatio/people.
2. if you saved by working hard, try to relax and have fun for couple of months ( dont waste all of em )
3. If that was a bullshit, keep it with you. It will fertilize your brain later.
4.  If you really into stock, be a day trader as  you have enough for that but stock is not a good idea at this time .
5. Franchise suggestion mentioned above seems smart to me .

If i were you, I would try to  fu*k at least one girl from every country in the world and possibly set my name in G book of world record.
