I have no time to scold, and I learned thirty years ago it was foolish to scold. I have enough trouble overcoming my own limitations without fretting over the fact God has not seen fit to distribute evenly the gift of intelligence.

John Wanamaker (1838–1922) American merchant, marketer, philanthropist, Postmaster General
Quoted in Herbert Adams Gibbons, John Wanamaker, Vol. 2 (1926)

Variant paraphrase: "It's foolish to scold people. I have enough trouble overcoming my own limitations without fretting over the fact that God didn't see fit to distribute brains equally."
