let everyone else call your idea crazy, just keep going, don't stop, don't even think about stopping until you get there, and don't give much think of where "there" is.
One strategy: "We've had three big ideas at Amazon that we've stuck with for 18 years， and they're the reason we're successful: Put the customer first. Invent. And be patient."
If you have an apple and I have an apple, and we exchange apples, we both still only have one apple. But if you have an idea and I have an idea, and we exchange ideas, we each now have two ideas.
