You are a Mayfly

Have you read about or seen mayflies?
They live in a population which matures at once from eggs.

And then ...
... for a day or two they are everywhere,
dancing around each other in large groups. They rest on every surface available to them.

Life for them is intense Imagine doing all you want in a day.
We all are mayflies.

But as Gautama put it, "You think you have time."
