When this happened nothing changed, no Hollywood style lifestyle change happened for me.
I was still the same person, I took the money and invested some in SP500 and Tbills and bought a 20,000 sq ft land in India (my wife is from North India).
Started a business of branding and selling items in India (there is huge money to be made on Amazon India, you can't even find 10% of the inventory that's actually in the US)
