A mature person is one who does not think only in absolutes, who is able to be objective even when deeply stirred emotionally, who has learned that there is both good and bad in all people and in all things, and who walks humbly and deals charitably with the circumstances of life, knowing that in this world no one is all knowing and therefore all of us need both love and charity.
You gain strength, courage and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, 'I have lived through this horror. I can take the next thing that comes along.' You must do the thing you think you cannot do.
It takes courage to love, but pain through love is the purifying fire which those who love generously know. We all know people who are so much afraid of pain that they shut themselves up like clams in a shell and, giving out nothing, receive nothing and therefore shrink until life is a mere living death.
