The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, 'I was wrong'.
Our dilemma is that we hate change and love it at the same time; what we really want is for things to remain the same but get better.
Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.
An idealist believes the short run doesn't count. A cynic believes the long run doesn't matter. A realist believes that what is done or left undone in the short run determines the long run.
The principal difference between love and hate is that love is a irradiation, and hate is a concentration. Love makes everything lovely; hate concentrates itself on the object of its hatred.
