Everything I Need to Know I Learned From RPGs
Featuring invaluable lessons drawn directly from TTRPGs such as Dungeons & Dragons, Pathfinder, Starfinder, Blades in the Dark, Fiasco and other TTRPGs (Always check for traps;" "Never underestimate the power of a short rest;" "Don't feed the trolls") as well as in-depth analyses of the ways in which these games' character archetypes can be successful models for varying approaches to life ("Rage is My Armor: How to Live Like a Barbarian and Keep Your Job"), this player's handbook for the game of life also features high concept illustrations of (and strategies for defeating) horrifying real-world monsters like that pile of junk in the garage, the soul-sucking ghost of nostalgia and the many-headed hydra that is the work/life balance.
With more hilarious, practical lessons than you can fit in a bag of holding, and referencing more than a dozen popular tabletop roleplaying games, it's a self-improvement book for anyone seeking guidance (both the spell and the advice) in their daily lives.
