1. Take a road trip. Mapping the route, singing at the top of your lungs, and discovering new towns with friends is the ultimate bonding experience.
2. Learn to play a musical instrument. I can play only a few chords, but I love the expressive power of music -- and the possibility that one day you can learn to create something beautiful through it.
3. Go skinny-dipping! It's the most liberating thing ever. You have to let go of your insecurities when you take off your clothes. But you're hidden by the water -- so it's like bending the rules. Who decided we have to wear clothes anyway?
