Lucius Annaeus Seneca 
Seneca’s Morals of a Happy Life, Benefits, Anger and Clemency 

There is not any thing in this world, perhaps, that is more talked of, and less understood, than the business of a happy life . It is every man’s wish and design; and yet not one of a thousand that knows wherein that happiness consists. We live, however, in a blind and eager pursuit of it; and the more haste we make in a wrong way, the further we are from our journey’s end. Let us therefore, first , consider “what it is we should be at;” and, secondly , “which is the readiest way to compass it.” If we be right, we shall find every day how much we improve; but if we either follow the cry, or the track, of people that are out of the way, we must expect to be misled, and to continue our days in wandering in error. Wherefore, it highly concerns us to take along with us a skilful guide; for it is not in this, as in other voyages, where the highway brings us to our place of repose; or if a man should happen to be out, where the inhabitants might set him right again: but on the contrary, the beaten road is here the most dangerous, and the people, instead of helping us, misguide us. Let us not therefore follow, like beasts, but rather govern ourselves by reason , than by example .
