Whoever in trouble and sorrow needs your help, give it to him. Whoever in anxiety or fear needs your friendship, give it to him. It isn't important whether he likes you. It isn't important whether you approve of his conduct. It isn't important what his creed or nationality may be.
The point... is to dwell upon the brightest parts in every prospect, to call off the thoughts when turning upon disagreeable objects, and strive to be pleased with the present circumstances.
