What is a life changing amount of money for you?

Since we are from all over the world, I want to know how much you need to actually change your life?

I'm from the most expensive city on earth, Zurich Switzerland. I need at least half a million swiss Francs (600k USD) to buy a house with 20% down. Median house price in Zurich is 3.2 million.

Really life changing for me would be 1+ million.
