We all sorely complain of the shortness of time, and yet have much more than we know what to do with. Our lives are either spent in doing nothing at all, or in doing nothing to the purpose, or in doing nothing that we ought to do. We are always complaining that our days are few, and acting as though there would be no end of them.
Seneca the YoungerThe true felicity of life is to be free from anxieties and pertubations; to understand and do our duties to God and man, and to enjoy the present without any serious dependence on the future.
Seneca the YoungerThe place one's in, though, doesn't make any contribution to peace of mind: it's the spirit that makes everything agreeable to oneself.
