It is 100% over-rated.
I don't mean that we should all act like we are 13 years old again. I don't want to worry about boobs, braces, boys, or bratty friends.
I am glad I know how makeup should be applied, that Payless shoes are just as cool as the name brand, and that I don't have to check in with my parents when I get home late at night.
I simply mean that we should never get to the point where we take ourselves too seriously.
Laugh at yourself. Dang it.
Befriend a teenager enough to remember what it was like to be one. Listen to some old school Brittney Spears or Spice girls, and see if those old feelings and dance moves come rushing back again.
Pay your bills. Be good to your children. Love your other half. Don't get traffic tickets....and laugh when you forget.
