We do not stop engaging in activity for entertainment and recreation because we are old; we grow old because we stop having fun. There are secrets to remain young, being joyful and achieving success. Growing up or growing old? The elderly usually don't have sorrow for what they did, but rather for things they did not do. The only people who fear death are those with regrets. Grow up by always finding the opportunity in change, doing what you want and what is right without regrets.
