The double standard of morality will survive in this world so long as the woman whose husband has been lured away is favoured with the sympathetic tears of other women, and a man whose wife has made off is laughed at by other men.
I confess that altruistic and cynically selfish talk seem to me about equally unreal. With all humility, I think 'whatsoever thy hand findeth to do, do it with thy might,' infinitely more important than the vain attempt to love one's neighbour as one's self. If you want to hit a bird on the wing you must have all your will in focus, you must not be thinking about yourself, and equally, you must not be thinking about your neighbour; you must be living with your eye on that bird. Every achievement is a bird on the wing.
If a ship has been sunk, I can't bring it up. If it is going to be sunk, I can't stop it. I can use my time much better working on tomorrow's problem than by fretting about yesterday's. Besides, if I let those things get me, I wouldn't last long.
