Interpretation
Age is not determined by years but by one's quest for knowledge and purpose.

Never spend your money before you have earned it.
Never look for a worm in the apple of your eye.
With all its sham, drudgery, and broken dreams, it is still a beautiful world. Be cheerful. Strive to be happy.
