Big breakthroughs typically follow a seven-step path:

1. First, no one's heard of you.
   
2. Then they've heard of you but think you're nuts.
   
3. Then they understand your product, but think it has no opportunity.
   
4. Then they view your product as a toy.
   
5. Then they see it as an amazing toy.
   
6. Then they start using it.
   
7. Then they couldn't imagine life without it.
   

Technology does not drive change. It is our collective response to the options and opportunities presented by technology that drives change.
