“Although it is very right to think about the future, it is very wrong to be controlled by it.
"The difficulty with people who are prey to these fears is that they are controlled by the future, they are dominated by thoughts of it, and there they are wringing their hands, doing nothing, depressed by fears about it. In fact, they are completely governed and mastered by the unknown future, and that is always wrong. To take thought is right, but to be controlled by the future is all wrong.”
