Abd Er-Rahman III of Spain:

I have now reigned about 50 years in victory or peace, beloved by my subjects, dreaded by my enemies, and respected by my allies. Riches and honors, power and pleasure, have waited on my call, nor does any earthly blessing appear to have been wanting to my felicity. In this situation, I have diligently numbered the days of pure and genuine happiness which have fallen to my lot. They amount to fourteen. (960 C.E.)

Albert Camus:

You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.
