On Being includes a post by Parker J. Palmer that, while not intended to focus on Father’s Day, applies to parenting: Have the courage to make small contributions knowing that there is a cumulative power in your imperfections.
Palmer writes (excerpt):
[Leonard] Cohen’s lyrics [in Anthem] remind me that there is a particular kind of courage in the willingness to make one’s small, imperfect offering — saying, in effect, “I don’t have much to give, but I give it gladly as a contribution to the common good.” When we have that kind of courage, we encourage each other. And as more and more people make their small offerings, the cumulative effect can become something big.
