It's often thought that crazy youth grow quieter. Let them do wild things, that's how they learn!
However that's not always the wisest as choices you make when you're young, for studies, work, love can be very costly later on.
Not to say they're bad choices, but it's when you're older, with savings and experience, that you're in a good position to test, go wild and fail if needs be.
The older you become, the more risks you should take!
