I like the people I work with. So, I would give the 2 weeks notice and make sure the transition works out well. They are my friends, and I would ensure they aren't left in the lurch.
So, $10million.... not much, but, it will do just fine.
1) Buy / build an apartment building. A six 2 bedroom (2 apartments per floor), near major transportation. The rent alone (~ $2,000 to $2,500) would be a really nice source of income for generations to come,.. and I would most likely live in one of the apartments.
2) Travel; Japan, Australia, Europe (Western / Eastern) and Netherlands area (summer).
3) Open a comic book / video game store. A huge warehouse like store, stocked with tons of video games and comic books. Security up the wazoo. And, a coffee/cafe shop on the side - no entry in the cafe with comics from the store, unless you have a receipt,.. which will give you 50% off your first 2 beverages and up to 5 baked good!
I think after all of that, I should have about $5 million left over. And, the businesses should be pouring in some nice scratch.
