“Until you make the unconscious conscious”: Although this quote by Jung is popular, I had trouble tracking down the original source. It’s probably a paraphrase of this passage: “The psychological rule says that when an inner situation is not made conscious, it happens outside, as fate. That is to say, when the individual remains undivided and does not become conscious of his inner opposite, the world must perforce act out the conflict and be torn into opposing halves.” For more, see C. G. Jung, Aion: Researches into the Phenomenology of the Self (Princeton, NJ: Princeton University Press, 1959), 71.

many ways to use implementation intentions: For the term habit stacking, I am indebted to S. J. Scott, who wrote a book by the same name. From what I understand, his concept is slightly different, but I like the term and thought it appropriate to use in this chapter. Previous writers such as Courtney Carver and Julien Smith have also used the term habit stacking, but in different contexts.

acquired a scarlet robe: Encyclopædia Britannica, vol. 8 (1911), s.v. “Denis Diderot.” Diderot’s scarlet robe is frequently described as a gift from a friend. However, I could find no original source claiming it was a gift nor any mention of the friend who supplied the robe. If you happen to know any historians specializing in robe acquisitions, feel free to point them my way so we can clarify the mystery of the source of Diderot’s famous scarlet robe.

The Diderot Effect states: Juliet Schor, The Overspent American: Why We Want What We Don’t Need (New York: HarperPerennial, 1999).
which was created by BJ Fogg: In this chapter, I used the term habit stacking to refer to linking a new habit to an old one. For this idea, I give credit to BJ Fogg. In his work, Fogg uses the term anchoring to describe this approach because your old habit acts as an “anchor” that keeps the new one in place. No matter what term you prefer, I believe it is a very effective strategy. You can learn more about
