John Milton

Better to reign in hell than serve in heav'n.

Accuse not Nature, she hath done her part; Do thou but thine.

Most men admire Virtue, who follow not her lore.

Who overcomes By force, hath overcome but half his foe.

Revenge, at first though sweet, bitter ere long, back on itself recoils.

The mind is its own place and in itself can make a heaven of hell, a hell of heaven.
