Shakespeare

The road to true love never did run smooth.

Love is merely madness.
Shakespeare - Hamlet III, iv, 156-160.
O, throw away the worser part of it, And live the purer with the other half.

And this our life, exempt from public haunt, finds tongues in trees, books in running brooks, sermons in stones, and good in everything.

Love all, trust a few, do wrong to none.

It is not in the stars to hold our destiny but in ourselves.

Why then the worlds mine oyster, Which I with sword shall open.
Shakespeare - Hamlet, Act I, Scene 3
To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.
Shakespeare - Hamlet
There is nothing either good or bad, but thinking makes it so.
Shakespeare - Romeo and Juliet
Tempt not a desperate man.

How far that little candle throws his beams!
So shines a good deed in a weary world.

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