I find the sustained practice of gratitude difficult. It does not always come easily or naturally to me, and I effortfully have to redirect ingrained tendencies to take life for granted. That may be the only thing I have in common with Einstein. He had to remind himself, a thousand times a day by his count, of how much he depended on other people. A thousand times a day, I too have to remind myself to be grateful and to remember how much I depend upon other people.— Robert Emmons in Thanks!
