As we get older we become more and more skeptical, and judgmental of others. We start to loose that child like quality, "life hardens the heart" the Buddha says.
Jesus says to enter the Kingdom of Heaven we must be as a child!
When is the last time you felt real child like? When is the last time you cranked the music and danced?
Don't wait for tomorrow, do it now! (unless you are at work lol, or it's 2 am and your household is asleep, you get the picture)
