"Boredom is the failure of the search for external fulfillment and refusal to look at what drove the search. Boredom is deep-rooted resistance to experiencing emotions after all efforts to distract attention from them have been ineffective. The root of boredom is resistance to painful emotions. This is the root of workaholism and perfectionism, also. In some cases the root produces boredom first, and then an escape into workaholism or perfectionism. In other cases, the workaholism or perfectionism comes first, and then boredom." (p. 193)

"Earlier, we spoke about the stress of boredom. This is also a change stressor because the lack of change often brings on boredom. When we are not excited about what we are doing, we often become depressed, irritated, and uptight. Variety is the spice of life, and without it our senses become dull or we become jumpy." (p. 145)
