„To have left undone what thou shouldst have done: to have lost the faithfulness, the reverence, the modesty that is in thee!“
— Epictetus philosopher from Ancient Greece 50 - 138
Context: Canst thou judge men?... then make us imitators of thyself, as Socrates did. Do this, do not do that, else will I cast thee into prison; this is not governing men like reasonable creatures. Say rather, As God hath ordained, so do; else thou wilt suffer chastisement and loss. Askest thou what loss? None other than this: To have left undone what thou shouldst have done: to have lost the faithfulness, the reverence, the modesty that is in thee! Greater loss than this seek not to find! (91).

„It turns out you left something rather important off your career plan: for example, there’s no ticky-box on the diagram for HAVING A LIFE—TASK COMPLETED. And so you kept putting it off, and de-prioritized it, and put it off again until the law of conservation of shit-stirring dragged it front and centre and lamped you upside yer heid, as your clients might put it.“
„There is a maxim, 'Never put off till tomorrow what you can do today.' It is a maxim for sluggards. A better reading of it is, 'Never do today what you can as well do tomorrow,' because something may occur to make you regret your premature action.“
— Aaron Burr American Vice President and politician 1756 - 1836

„You don't have to be intelligent, but I think you have to be open to possibilities and willing to explore. The only stupid people are those who are arrogant and closed off.“

Iraq? They just need to think it through (2007), Context: There isn't just one point; it takes time to learn. You don't have to be intelligent, but I think you have to be open to possibilities and willing to explore. The only stupid people are those who are arrogant and closed off.
„The key is this: Meet today's problems with today's strength. Don't start tackling tomorrow's problems until tomorrow. You do not have tomorrow's strength yet. You simply have enough for today.“

The Tragic Sense of Life (1913), XI : The Practical Problem, Context: And what is its moral proof? We may formulate it thus: Act so that in your own judgment and in the judgment of others you may merit eternity, act so that you may become irreplaceable, act so that you may not merit death. Or perhaps thus: Act as if you were to die tomorrow, but to die in order to survive and be eternalized. The end of morality is to give personal, human finality to the Universe; to discover the finality that belongs to it — if indeed it has any finality — and to discover it by acting.
