The haiku lets meaning float; the aphorism pins it down.

Failure makes us envious. Success makes us greedy.

The life of pleasure breeds boredom. The life of duty breeds resentment.

Children pay little attention to their parents' teachings, but reproduce their characters faithfully

Like a frog, the aphorist waits for something to fly by that he can catch with his tongue.

Sometimes I discover I have changed my mind because I have forgotten what I used to think.

The shades of respectability begin to close about the greying head.
