Largeness is a lifelong matter - sometimes a conscious goal, sometimes not. You enlarge yourself because that is the kind of individual you are. You grow because you are not content not to.

You achieve stature only by being good enough to deserve it, by forcing even the contemptuous and indifferent to pay attention, and to acknowledge that human relations and human emotions are of inexhaustible interest wherever they occur.

wherever you find the greatest good, you will find the greatest evil, because evil loves paradise as much as good.
