Money won't buy you happiness, although if you know what you want, money can buy you some freedom and freedom will for sure bring you happiness. I've calculated, I need like 3 million euro, then I can buy a little studio/apartment somewhere in SE Asia, living there. Cities like BKK can be fun, if you don't have to work 9 to 5 of course. Then I'll probably come back to Europe in the summer for some parties and festivals. The rest of money I'll just enjoy life to its best :D
But maybe if I make so much money one day, my mind will change? Will I want more money, instead of enjoying life as I expect now? No idea. But that's what I calculated for now :D
