For nothing outside my reasoned choice can hinder or harm it -- my reasoned choice calone can do this to itself. If we would lean this way whenever we fail, and would blame only ourselves and remember that nothing but opinion is the cause of a troubled mind an uneasiness, then by God, I swear we would be making progress.
-- Epictetus, Discourses, 3.19.2-3
"Start where you need to. Even one minute without playing the blame game is progress in the art of living."
