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 neighbor 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 neighbor: you must be living in your eye on that bird. Every achievement is a bird on the wing.
