I'm planning to have a million before I turn 25, I'm 18 now, so that's plenty of time

But off course, the most important thing is indeed waht you do with it. I don't think I'd really change my life because of the amount of money I have. If I magically got 1 million$ today, I'd probably buy a boat for my mother (something she's been dreaming of for all her life) , and I'd just invest the rest I think :-).
I just want to make sure I never have to worry abouy money and that I can help other people realise their dreams and projects.
