It's a known fact that children and young adults see things differently than older people. When young, curiosity, enthusiasm and faith in success overwrite the disappointments and distrust of a positive outcome... It's also an age when we are not yet tied down by material things and possessions... As older adults though, it's like we completely forgot that we are free to change our life, if we are not happy with it. It doesn't necessarily mean that it will became great (or even better), the point is that we don't even try. Because we have to take care of too many things and there is too much to lose... at least that's how we perceive it from the low vantage point we stand. And that makes change look not only scary, but dauntingly impossible or simply unattractive.
The image was also about that, learning to hold tight while letting go, embracing the scary thrill of a powerful swing thrusting us up in the sky... That "happy scary" of a new exciting adventure, the feeling of being light on your feet and thoughts, trustful and hopeful...at peace with your mind and heart... and just live your life, not somebody else's.
