Well, having a million Euro is not much but it's enough to live a decent life without working for the rest of my life. I could even buy a decent house.
What I would do is to invest a part of that in some way to make it grow over time. Then I will use a part to boost my music career and get into event organization because that's what I like to do for passion. I'm not interested in yachts, luxury and big houses. I'd like to travel to some places that I'm particularly interested in.

But it's just enough for me to live my life without worrying about not having enough money to pay the bills and make my music in peace and don't waste my time in useless jobs.

Then, if the millions are many, for sure I'm going to spread the wealth with others that need it. I don't know how, I'm not a fan of charity organizations. I'd prefer to give money away personally to who I think could make a good use of it in society
