Life is a sage’s university; hardship is his professor.

A book is a small library you can fit into your pocket.

Life is a thorough university; pain and hardship are its distinguished professors.

You cannot wake up one who refuses to open his eyes.

The first professor you meet in life is your mother; the second is hardship, and the last is death.

My words are my thesis, my actions are my dissertation, and my life is my philosophy.
