The Big Book of 30-Day Challenges: 60 Habit-Forming Programs to Live an Infinitely Better Life by Rosanna Casper

adventurous informative inspiring fast-paced

3.0

Very fast read with a good variety of ideas and encouragement.  The author provides general suggestions on how to approach the challenge, occasionally with week-by-week or day-by-day plans.  One problem I found was regular references to find more information on https://hackerella.com/30daybook which elicits a "404 Not Found" error.
