Life is full of illustrations.

We are continually coming up to doors which stand open for a little while and then are shut.

Father Time is there with inverted hour-glass.

A young man is lying at his ease on a luxurious couch, while beside him is a table spread with rich fruits and viands.
Passing by him toward an open door are certain figures which represent opportunities; they come to invite the young man to nobleness, to manliness, to usefulness, to worth.
