Peter Hollins is an American self-help author and researcher of psychology and human behavior, based in Seattle, Washington. He holds a BS and an MA in psychology and worked in private practice before turning to full-time writing. Since debuting with the "Live a Disciplined Life" series, Hollins has published more than 100 books on self-discipline, social skills, and productivity, several translated into other languages, building a large readership on Amazon and Audible within the self-improvement genre. The Science of Self-Discipline distills psychological research — including Roy Baumeister's ego-depletion studies and Walter Mischel's marshmallow test — into practical techniques for building willpower and resisting temptation. Hollins writes prolifically and independently, self-publishing most of his catalog rather than working through a traditional publishing house, and his books circulate primarily among readers seeking actionable self-improvement guidance rather than in literary or academic circles.
