From my high school days of obsessive rhyming...

OPTIMIST'S CLUB

As I write this
The world will turn.
Water will run
And fire will burn.
Trees will grow,
And insects will die
As you wipe off the bug
That flew in your eye.
How many times
Have you seen flowers bloom?
Day in, day out,
With its scented perfume.
Every single day,
As the world turns,
Every single day,
As your stomach churns,
The green Earth lives,
And nature will thrive.
So just sit down and think:
Isn't it great to be alive?
