The important thing...

Same task as last year, new batch of students. Here are a couple:

The important thing about measurement is that it puts things in perspective.
The speed in which life pulls you from an infant to a grown-up,
How deeply you can fall in love,
How much weight you lost to fit in the prom dress,
How time slips with a tick and a tock of a clock,
How the years of your life are not as infinite as kilometers.
But the important thing about measurement is that it puts things in perspective.

The important thing about a cone is that it holds ice cream.
It has a circular base and a pointy top.
Its Surface Area is (pie x radius) x (radius + height).
Its volume is 1/3 Base x height.
It is a very complicated geometric figure.
But the most important thing about a cone is that it holds ice cream.

...I'm absolutely exhausted, but the important thing about life is that I love what I do.
