OK ... but once you've got cash in hand, what then? Here's an unconventional list of potential next steps for brand-new billionaires. Have fun ... and good luck!

1. Get a new phone number ... and keep it unlisted. This will help avoid those unwanted calls.

2. Avoid contact with all the friends and relatives coming out of the woodwork whom you have not heard from in years and years.

3. Dust off that cabana wear. It's high time for a vacation or that country club membership.

4. Start learning new languages for all that travel you will be doing.

5. Prepare a proper way to tell your boss he (or she) was a real pain in the butt and you quit.

6. Come up with a great name for your new yacht.

7. Decide if now is the time to buy that new villa in Tuscany. Or is it a buyer's market on the French Riviera?

8. Remind your kids they still need to get jobs and support themselves. No free lunch!

9. Is buying matching sports cars too bold of a move?

10. Finally, give money to charities you believe in. It's the right thing to do.
