" You could resent yourself for your imperfect enjoyment of your life, but that seems to me like a never-ending chore. A thankless one, too. I think that if we really knew how good our lives were while they were good, we’d be too scared to do anything, change anything. We’d never take a risk, or explore, or grow. You can hate yourself for not fully appreciating your happy days while you had them, or you could look back and be warmed by the memory, couldn’t you? "
