Walking backwards

I just read something in the afternoon while flipping through some blogs...it sorta went like this...

"Something to try and (not) do: Walk across a busy street backwards.

Your back leads you forward but your eyes never see ahead of you, they can only see behind. You are walking almost blind, with only hindsight to guide you. That is life.

In life we never can know truly what lies ahead of us. Only what we left behind. Watch out for stray cars."
