Good character consists of recognizing the selfishness that inheres in each of us and trying to balance it against the altruism to which we should all aspire. It is a difficult balance to strike, but no definition of goodness can be complete without it.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
