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.
On haters: "If you never want to be criticized， for goodness' sake don't do anything new."
When you believe in a thing,believe in it all the way,implicitly and unquestionable.
I only hope that we never lose sight of one thing - that it was all started by a mouse.
