Consider the following

Heading off to vacation is a strange thing. As a kid you are expectant for weeks
upon end. The expectancy adds to the experience. As an adult it's different. We're
so busy it seems that expectancy only gets experienced as we sit in the plane or
in our car on the way to the cabin. There are elements in childhood that we know
we need. I think expectancy is one of those elements.

Expectancy is different than dissatisfaction. On the one hand we have an excited
tension but on the other we have frustration at our circumstances. Maybe that's
why adults have a harder time with expectancy. So lets dream about the future
and enjoy the day.
