I always love these topics and I love seeing how differently everyone would use the money!
First and foremost, I strongly believe in the sentiment that you should live your life now the same way you would live if you had ALL THE MONEY. Meaning - create a lifestyle that you are happy enough with so that it is not dependent on having ALL THE MONEY. (My husband always likes to tell our friends who question our slightly alternative lifestyle that we "are always aiming to live our best, 'poor' life"). :-)
That being said, I do have some plans I am working towards that would happen a lot sooner if I had access to ALL THE MONEY including:
1. Go get tacos and fancy-ass local craft beer to celebrate good fortune
2. Hire accountant/lawyer to make a plan for the money; set aside at least 80% of the money to grow/invest.
3. Quit the job that requires sitting in front of a screen and on my ass all day... Pronto.
4. Pay off parents mortgage and build them the front porch which they have wanted for years now. Make sure there is enough money to always take care of them (I'm an only child).
5. Buy a smallish used RV and set off with the hubs and pups for a year-long American Road Trip
6. Train for and participate in this:

8. Travel to exotic locale and complete dive-master training.
9. Dedicate rest of life and money to cleaning the oceans and educating people on how to live in harmony with our planet.
10. Once my time is up, donate ALL THE MONEY to no-kill animal shelters around the world and the Surfrider Foundation (unless I have started a foundation of my own by then)!
For reference, me and the hubs are DINKS, early 40s, perpetual renters, dual UK/US citizens, have two fur-babies with no plans for kids.
