William Shakespeare

Words are easy, like the wind;
Faithful friends are hard to find.

The course of true love never did run smooth.

To weep is to make less the depth of grief.

Be not afraid of greatness [...]. Some are born great, [...] some achieve greatness, [...] and others have greatness thrust upon them.

Our doubts are traitors, and make us lose the good we oft might win, by fearing to attempt.

Love looks not with the eyes, but with the mind.
