Impossible Possibilities
600 years ago we thought the earth was flat. Just over 100 years ago we thought it was impossible for man to fly. Just over 50 years ago we still thought that steam powered was the way to travel by train. 40 years ago we hadn't put a man on the moon.
Every day we're faced with impossibilities. We're told, "You can't do that; it'll never work."
But you know... an impossibility is simply a problem that we haven't conquered yet. Consider that as you next commute to work on your electric train.
