"5. If you could go back in time and do one thing differently, what would it be?<p>I wish I had taken advantage of all the free time I had in high school and actually learned stuff, instead of spending so much time hanging out with friends."<p>Really?

They're not exclusive, but surely spending all free time studying and not socializing is bound to rob you of valuable experiences.
