Be "Childish"

No; I don't mean throw tantrums until you get what you want, or shake off responsibilities (even though, for a day, it might be nice).

I mean, be fascinated by the world around you. Be curious, and playful. Use that energy you've been storing so long for Lord-knows-what! There is SO MUCH you don't know; even about the things you are around every day. Discover these things. Try to look at things from a child's perspective. It'll give you a new look at life.
