Nature which governs the whole will soon change all things which you see, and out of their substance will make other things and again other things... in order that the world may be ever new.
Marcus AureliusNeither in thy actions be sluggish nor in thy conversation without method, nor wandering in thy thoughts, nor let there be in thy soul inward contention nor external effusion, nor in life be so busy as to have no leisure.
Marcus Aurelius
