博客來當今心理學界最閃耀的學者，
教我們如何定義，進而實踐心理豐富度，
活出更豐盛、更圓滿的美好人生。
究竟何謂「美好的人生」？心理學家們展開辯論，各自提出研究報告。1984年，艾德‧迪安納（Ed Diener）發表了一篇聚焦在「快樂」（happiness）的論文；五年後，他的競爭對手提出聚焦於「目的和意義」（purpose and meaning）的模型。如今，心理學界受矚目的學者大石茂弘（Shigehiro Oishi）則提出另一種論點，關注長期被眾人忽視的第三個維度——「心理豐盛」（psychological richness）。
對許多人來說，美好人生是走在廣受眾人認可的道路，維持穩定、舒適的生活。作者以自己的父親為例，他的父親一直生活在日本的山間小鎮，總是把家人的需求置於自己之上。世代以來，多數人也選擇走在類似的穩健道路上，但大石懷疑，這是否會是通往美好人生的最佳路徑？
大石獲獎的研究報告指出，一個人的好奇心、探索力、和經驗的多寡決定了心裡豐盛度，只要勇於接受挑戰、樂於學習新事物，無論是正面或負面的經驗，都能讓人成長，進而活出美好人生！生動的文筆和豐富的例證，為我們指出一條通往更加圓滿、少有遺憾的人生新道路。(文/博客來編譯)
好評推薦：
「有些人渴望在人生中得到的，不僅僅是幸福，而是擁抱生命的各種樣貌與可能。他們希望自己的人生如同一個偉大的故事、一場偉大的旅程，充滿曲折起伏，讓人得以在過程中見證正不同類型的生命之美。過往的心理學鮮少照顧到這群人，他們大多只能從浪漫的文學作品中尋得指引和知音，如今這本書將提供第三維度的全新見解來詮釋美好人生，包括如何找到可能最合適你的人生方向。」——紐約大學商學院教授、《失控的焦慮世代》（The Anxious Generation）作者強納森‧海德特（Jonathan Haidt）
「每週都有關於幸福和意義的新書上市，以致於很難有一本書能從中脫穎而出。然而，大石茂弘做到了！身為心理學領域最閃亮的明星之一，他動人的文筆、原創的觀點，引人深思。這本書將改變你對美好人生的看法。」——《強大內心的自我對話習慣》（Chatter）作者伊森‧克洛斯（Ethan Kross）
A NEXT BIG IDEA CLUB MUST-READ BOOK - From one of our foremost psychologists, a trailblazing book that turns the idea of a good life on its head and urges us to embrace the transformative power of variety and experience
For many people, a good life is a stable life, a comfortable life that follows a well-trodden path. This is the case for Shigehiro Oishi’s father, who has lived in a small mountain town in Japan for his entire life, putting his family’s needs above his own, like his father and grandfather before him. But is a happy life, or even a meaningful life, the only path to a good life?
In Life in Three Dimensions, Shige Oishi enters into a debate that has animated psychology since 1984, when Ed Diener (Oishi’s mentor) published a paper that launched happiness studies. A rival followed in 1989 with a model of a good life that focused on purpose and meaning instead. In recent years, Shige Oishi’s award-winning work has proposed a third dimension to a good life: psychological richness, a concept that prioritizes curiosity, exploration, and a variety of experiences that help us grow as people.
Life in Three Dimensions explores the shortcomings of happiness and meaning as guides to a good life, pointing to complacency and regret as a ＂happiness trap＂ and narrowness and misplaced loyalty as a ＂meaning trap.＂ Psychological richness, Oishi proposes, balances the other two, offering insight and growth spurred by embracing uncertainty and challenges.
In a lively style, drawing on a generation of psychological studies and on examples from famous people, books and film, Oishi introduces a new path to a fuller, more satisfying life with fewer regrets.
