Vaccinations are probably the single greatest advancement of human well-being in the past one hundred years. One study
found that the WHO’s global vaccination campaign in the 1980s likely prevented more than twenty million cases of dangerous
diseases worldwide and saved $1.53 trillion in health care costs. The only diseases ever eradicated entirely were eradicated due to
vaccines. This is part of why the antivaccination movement is so infuriating. See Walter A. Orenstein and Rafi Ahmed, “Simply
Put: Vaccinations Save Lives,”

Wealthier countries, on average, have higher suicide rates than poorer countries. Data can be found from the World Health
Organization, “Suicide Rates Data by Country,” http://apps.who.int/gho/data/node.main.MHSUICIDEASDR?lang=en. Suicide is
also more prevalent in wealthier neighborhoods compared with poorer neighborhoods. See Josh Sanburn, “Why Suicides Are
More Common in Richer Neighborhoods,”

Each of these is true, by the way.

My three-part definition of hope is a merging of theories on motivation, value, and meaning. As a result, I’ve kind of
combined a few different academic models to suit my purposes.
The first is self-determination theory, which states that we require three things to feel motivated and satisfied in our lives:
autonomy, competence, and relatedness. I’ve merged autonomy and competence under the umbrella of “self-control” and, for
reasons that will become clear in
chapter 4
, restyled relatedness as “community.” What I believe is missing in self-determination
theory—or, rather, what is implied but never stated—is that there is something
worth being motivated for, that there is something
valuable in the world that exists and deserves to be pursued. That’s where the third component of hope comes in: values.
For a sense of value or purpose, I’ve pulled from Roy Baumeister’s model of “meaningfulness.” In this model, we need four
things to feel that our life is meaningful: purpose, values, efficacy, and self-worth. Again, I’ve lumped “efficacy” under the “self-
control” umbrella. The other three, I’ve put under the umbrella of “values,” things we believe to be worthwhile and important and
that make us feel good about ourselves. Chapter 3 will dissect at length my understanding of values. To learn more about self-
determination theory, see R. M. Ryan and E. L. Deci, “Self-Determination Theory and the Facilitation of Intrinsic Motivation,
Social Development, and Well-being,”
American Psychologist 55 (2000): 68–78. For Baumeister’s model, see Roy Baumeister,
Meanings of Life (New York: Guilford Press, 1991), pp. 29–56.
