Planning experts advise visualizing the result you want.
Focusing on the end result helps with motivation and holds up
a picture to your brain saying, "this is what I want."

Remember the times when you study faces? There are some great 
wonderful old faces that sparkle. No matter how many wrinkles they
have they glow with warmth, energy, enthusiasm, and kindness.
Then there are faces that look sour or wrinkle up like prunes.

Certainly some people's heredity and facial structure put them at
a disadvantage in having an engaging, loveable face. That's all
the more reason they need to to make sure they have smile lines
rather than frown lines.

Research finds that in presidential and other political races the
more optimistic candidate is more likely to win. I think research
would also find the best face and best smile wins. Hence,
regardless of the soundness of their thinking and plans,
Ronald Reagan is more appealing than dour Bob Dole and
Bill Clinton is more appealing than fretful Joe Lieberman.
Perhaps the tipping point on George Bush vs. Al Gore or
John Kerry was Bush's more relaxed, engaging smile.

When I watch videos of myself speaking, I am struck with the
opportunities to smile more often. Who would you rather hear,
someone who smiles a lot or someone who is very serious?

I'm not advocating that you permanently have a just saved smile
glued on your face. The goal is to be expressive and smile much
of the time. The ideal is to have the expressiveness Norman
Rockwell described in President Eisenhower's face (see quote
below). By the way Ike's campaign slogan was "I like Ike."

This is a long way of saying, the more you smile now, the more
likely you are to have a face with great smile lines thirty years from now.
Start with the end in mind and you are likely to end up with
one of those sparkling, warm faces thirty years from now.
