If you are ever in need for affirmation of the goodness of most people, read Jayber Crow by Wendell Berry.
The beautifully written story of a small town barber, Jayber Crow explores the value of a modest life well lived. I recommended it on this site years ago and recently, while having some discussions with my son on life, I was reminded of how Berry's novel had affected my own interpretation of true achievement.
Most novels contain unpleasant surprises. In Jayber Crow, you may be surprised when people do good things and yet afterwards conclude, "Yes, I have seen more of that in life than its opposite."
There are many fine people out there. Jayber Crow takes us into the life of one.
