It may seem to your conceited to suppose that you can do anything important toward improving the lot of mankind. But this is a fallacy. You must believe that you can help bring about a better world. A good society is produced only by good individuals, just as truly as a majority in a presidential election is produced by the votes of single electors. Everybody can do something toward creating in his own environment kindly feelings rather than anger, reasonableness rather than hysteria, happiness rather than misery.
