(I don't have, have never had, nor ever will have that kind of money.) You have just earned your life's salary. Treat it as such. 7.5M Euros gives you approximately 100.000 after taxes per year for the rest of your life. Anywhere in Europe, that is a very healthy salary. So I think your focus, money wise, would be to try to stay ahead of inflation, longterm. Setup longterm investments, pay yourself a monthly 'salary'. If you want to do more startups, do them.
