According to Dr. David Song, a plastic surgeon and Associate Professor at the University of Chicago Hospitals, who was interviewed for a Straight Dope article, it takes 12 muscles to smile. Clearly our presenter last night lacks all 12 of those facial muscles as her look didn't match her words.
It's real simple people...mean what you say. If you're actually pleased to be presenting, SHOW IT. If you're not really all that jazzed to be there, DON'T LIE, simply avoid opening with a line that places you in an awkward spot. Why? Because we can tell your full of shit and authenticity truly matters.
Oh, and by the way, Guy Kawasaki in his bestselling book "Enchantment" encourages all of us to throw a few four-letter words in every now and then. Guy says it keeps the audience on their toes as long as it's not mean spirited or used too frequently.
I guess by now you've figured out that he and I agree. THANKS
