Say no to no.

Isn't it high time someone got negative about negativity?
Yes it is.
Look around.  The world is full of things that, according to nay-sayers, should never have happened.
"Impossible."
"Impractical."
"No."
And yet "yes."
Yes, men have played golf on the moon.
Yes, straw is being turned into biofuel to power cars.
Yes, yes, yes.
What does it take to turn no into yes?
Curiosity.  An open mind.  A willingness to take risks.
And, when the problem seems most insoluble, when the challenge is hardest, when everyone else is shaking their heads, to say:  let's go.
