Look back over the past, with its changing empires that rose and fell, and you can foresee the future, too.
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 AureliusBe not unwilling in what thou doest, neither selfish nor unadvised nor obstinate; let not over-refinement deck out thy thought; be not wordy nor a busybody.
Marcus Aurelius
