I know what happiness is, for I have done good work.

Make up your mind to be happy. Learn to find pleasure in simple things.

He is not dead, this friend; not dead, Gone some few, trifling steps ahead, And nearer to the end; So that you, too, once past the bend, Shall meet again, as face to face, this friend You fancy dead.

To have suffered ... sets a keen edge on what remains of the agreeable. This is a great truth and has to be learned in the fire.

Being happy enables you to be free from domination by the outside world.
