The mastery of nature is vainly believed to be an adequate substitute for self mastery.
Reinhold NiebuhrGod, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. Grant me the patience with changes that take time, appreciation of all that I have, tolerance of those with different struggles, and the strength to get up and try again, one day at a time.
Reinhold Niebuhr
