Well said Herodes
I once read the story about the brothers Orville and Wilbur Wright. For those uninformed, they invented the air-plane.
http://en.wikipedia.org/wiki/Wright_brothers for some more information.
Needless to say, few if any believed in what they were doing. Actually they were considered more as lunatics, even their own father said it was completely impossible to make an airplane fly.
They studied how sea gulls where glide flying and, so they wanted to create something similar, with propells attached to it.
They faced a lot of obstacles, but kept on pressing. Finally they had a plane that actually worked for short distances. Their father was a witness to one of their first flights, and he took of his hat, and his mouth was wide open. His sons had made it.
Believing is the first step in doing anything. If you don't believe you can make it, you can't.
As we all know, aviation has advanced greatly since that time, not to mention what impact it has on the world.
It's not impossible that in maybe some decades that everyone will laugh about the fact that bitcoin was something that wasn't something that could succeed.
When you read something like this,
