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 happened.
"Impossible".
"Impractical".
"NO".
And yet "yes".
Yes, continents have been found.
Yes, men have played golf on the moon.
Yes, straw is being turned into biofuel to power cars.
Yes,yes,yes.
What it does it take to turn 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.
