Seneca

“ The present offers only one day at a time, and each by minutes; but all the days of past time will appear when you bid them, they will suffer you to behold them and keep them at your will—a thing which those who are engrossed have no time to do. The mind that is untroubled and tranquil has the power to roam into all the parts of its life ”

“ For the last is the one over which Fortune has lost control, is the one which cannot be brought back under any man's power. But men who are engrossed lose this; for they have no time to look back upon the past, and even if they should have, it is not pleasant to recall something they must view with regret. They are, therefore, unwilling to direct their thoughts backward to ill-spent hours, and those whose vices become obvious if they review the past, even the vices which were disguised under some allurement of momentary pleasure, do not have the courage to revert to those hours. ”

“ Should I choose to divide my subject into heads with their separate proofs, many arguments will occur to me by which I could prove that busy men find life very short. But Fabianus, [1] who was none of your lecture-room philosophers of to-day, but one of the genuine and old-fashioned kind, used to say that we must fight against the passions with main force, not with artifice, and that the battle-line must be turned by a bold attack, not by inflicting pinpricks; that sophistry is not serviceable, for the passions must be, not nipped, but crushed. ”
