Don't let your imagination to be crushed by life as a whole. Don't try to pictures everything bad that could possibly happen. Stick with the situation at hand. ...Then remind yourself that past and present have no power over you. Only the present.
Marcus AureliusYou always own the option of having no opinion. There is never any need to get worked up or to trouble your soul about things you can't control. These things are not asking to be judged by you. Leave them alone.
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 AureliusIf you do the task before you always adhering to strict reason with zeal and energy and yet with humanity, disregarding all lesser ends and keeping the divinity within you pure and upright, as though you were even now faced with its recall - if you hold steadily to this, staying for nothing and shrinking from nothing, only seeking in each passing action a conformity with nature and in each word and utterance a fearless truthfulness, then the good life shall be yours. And from this course no man has the power to hold you back.
Marcus Aurelius
