Tac

“....let me tell you that the one sin I have come to fear more than any other is certainty. Certainty is the great enemy of unity. Certainty is the deadly enemy of tolerance. Even Christ was not certain at the end........Our faith is a living thing precisely because it walks hand in hand with doubt. If there was only certainty, and if there was no doubt, there would be no mystery, and therefore no need for faith.”
― Robert Harris, Conclave

“Compare yourself to who you were yesterday, not to who someone else is today.”
― Jordan B. Peterson, 12 Rules for Life: An Antidote to Chaos

“If you would not have a man flinch when the crisis comes, train him before it comes.”
― Lucius Annaeus Seneca

“If you remove your judgement of anything that seems painful, you yourself stand quite immune to pain. 'What self?' Reason. 'But I am not just reason.' Granted. So let reason cause itself no pain, and if some other part of you is in trouble, it can form its own judgement for itself.”
― Marcus Aurelius, Meditations
