Sure, when you'r "big" :) you have more power to decide, but as my mother always said to me: "More power will come with more responsability". Of course it's nice to get a car, and Travel away without ask my parent's first IF I could go and being possible to get a NO as answer. BUT, somehow, you didn't need to worry to pay bills, to look for money, too care if there were enougth food in the house, etc. It's sure less stress (not less worries) I believe that generally speaking, you have the worries you can carry according to your "brain's size" :)
The only thing you regret in life, is the risk you don't take.
