What do I Know?

When I was 10, what did I know?
When I was 20, I was surprised at how little my parents knew.
When I was 35, I was impressed at how much my parents were learning.
When I was 50, I began to realize that my parents really knew more than I had
given them credit for.
When I was 65, I began to realize my own ignorance and how immense it was.
And before I was even 80, I realized that wisdom does not come quickly, easily
or with idleness of thought.
After all, what do I REALLY know?
Let humility be thy goal.
