—Thomas Mann (1875–1955)
“Guilt is the most destructive of all emotions. It mourns what has been while playing no part in what may be, now or in the future. Whatever you are doing, however, you are coping, if you listen to your child and to your own feelings, there will be something you can actually do to make things right.”
—Penelope Leach (20th century)
“Any solution to a problem changes the problem.”
—R.W. (Richard William)
