Before you tell yourself that your idea is too ambitious, too unrealistic, too pie-in-the-sky; remember that once there were no planes. There were no rockets to take us into space. There were no computers.
Someone had to take the first leap. Someone had to build wings out of wood and try to fly. Someone had to look logic in the face and tell it to do one. That someone had the courage to try. And our world today is shaped by their efforts.
So don't shelve the crazy ideas because they're too far into the clouds. The very fact that they're crazy probably means you're on to a winner.
It's called Moonshot Thinking and Google are paying homage to it in this film. A sure shot of Friday inspiration.
