self-help book大多直譯為「自助書」，感覺從字面上不易理解。OED將定語self-help解釋為極少或不依靠他人的幫助，依靠自己的努力和能力達成某事、供養自己的行為或才能；今特指以這種方式控制或克服個人問題或情感問題的行為。（The action or faculty of using one's own efforts and resources to achieve something, or provide for oneself, with little or no assistance from others; (in later use) spec. the action of managing or overcoming personal or emotional problems in this way.）感覺比較接近於成功學書籍和心靈雞湯……
