It does not matter how much knowledge you have in your head,
or what your accomplishments are,
you will live a cold, friendless, isolated life, and will be unattractive,
unless you have come in close constant contact with others lives,
unless you have have cultivated your sympathies, and have taken a real interest
in others, have suffered with them, rejoiced with them, helped them.
