The following quote from our late prophet, Spencer W. Kimball, seems appropriate here:
I come to realize more and more as my experience broadens, the vast influence and power that a small minority may wield in this work, in politics, in religion, in social activities, everywhere you go. A small group, united in purpose, with definite goals may greatly influence the great majorities. Teachings, p. 178
