“Caution is often a virtue, but in your case you carry it too far. It’s a little flaw in your character and it shows in a multitude of ways. In your wary approach to problems in your work, for instance—you are always too apprehensive, proceeding fearfully step by step when you should be plunging boldly ahead. You keep seeing dangers when there aren’t any—you’ve got to learn to take a chance, to lash out a bit. As it is, you are confined to a narrow range of activity by your own doubts.”
