In Jeff's TED Talk
, he explains that the ideas in our heads come from the input we receive — what we see, hear, experience, dream, imagine, etc. When we write
, we share our unique window on the world (and its unique insights and perspectives) with others... thus becoming the "input" for the reader's mind. If we imagine the Earth as a giant brain and each person as a neuron... sharing our ideas back and forth is what makes the global brain function. You live a life no one else will ever know. By sharing what you see, you offer a one-of-a-kind contribution to our world. And since ideas spark ideas, you never know where that might lead.
