The right reading—often accidental—wakes up slumbers and gives needed goals to those who still have none. The right book or article has started many on the main road and off the detours.
A librarian, your boss, a book dealer, a teacher can help you pick the reading that will count. Often we just stumble across the right reading; that’s why it is wise to read many things. I accidentally stumbled into psychology. I was halfway through college, majoring in chemistry, and an assistant in the physics laboratory. Then one Christmas vacation I started to read a four-volume manual on experimental psychology by E. B. Titchener. At the end of the vacation I knew I was changing my vocation. My chemistry professor was disgusted. But the halfhearted chemistry student became an enthusiastic psychology student.
