The essays in How to Ruin Everything range from the absurd (how he became an international ivory smuggler) to the comical (his middle-school rap battle dominance) to the revelatory (his experiences with epilepsy), yet all are delivered with the type of linguistic dexterity and self-awareness that has won Watsky more than 765,000 YouTube subscribers. Alternately ribald and emotionally resonant, How to Ruin Everything announces a versatile writer with a promising career ahead.
