鄭重聲明：本書並無鼓吹人人單身的意圖，但如你經常性使自己陷入以下困境，請儘速服用本書──
 
　　✓為了逃避失戀的痛苦、為了不想一個人吃飯，而和一個你並沒有那麼喜歡的人交往。
　　✓為了討好你非常喜歡的人，而努力變成一個你自己都不認識的人。
　　✓為了讓戀情能夠繼續走下去而勉強自己。
　　✓因為失戀而陷入巨大的負面情緒，然後吃掉太多(其實沒有真的撫慰到你的)冰淇淋。
 
　　如果符合以上所有事項……相信我，你得認真「單身」一下才行。
 
　　生活絕對不只有經營感情而已，但單身卻讓人覺得像被判了死刑。為什麼單身就等於孤單呢？為什麼我們忙著經營與別人的關係，卻忘了經營與自己的關係？
 
　　經歷了一場讓人身心俱疲的離婚後，心理諮商師、暢銷書《I Used to Be a Miserable F*ck》作者約翰．基姆才發現，自己其實從未真的好好體驗孤獨的滋味──他的人生，總是不斷地在尋覓對象、約會、交往、分手，然後再從頭來過。基姆認真意識到，太過渴望透過他人證明自己的價值，讓他缺乏忍受孤獨的能力。他開始重新打造與自己的關係，不再因單身而認為自己不被需要，而是設法活得充實而富足。
 
　　基姆更進一步幫助了上千位客戶找到掙脫他人期望束縛、活出自我的解方，在本書中，從建立與自己的連結，到如何處理破碎關係和放手，帶領讀者打造全新的自己，基姆並以幽默風趣的文字分享了自己的經驗，告訴讀者：不論是單身、約會中，還是正在和伴侶共同生活，都得先找到自我價值，才有可能與他人建立真正有意義而美好的關係。(文/博客來編譯)

　　The author of I Used to Be a Miserable F*ck, The Angry Therapist, now teaches you how to prioritize your relationship with yourself and live a more meaningful life, whether you’re alone, dating, or with a partner.
 
　　There’s more to life than loving someone. But being single can feel like a death sentence. Why does being alone = being lonely? And why do we stop working on ourselves when we’re in a relationship?
 
　　After a painful divorce, “The Angry Therapist” John Kim realized he had never truly been on his own. He went on a journey to rebuild his relationship with himself, going from alone and disconnected to alone and fulfilled.

　　Kim has gone on to help thousands of clients find their own unique way to break free of expectations and finally live their truth. With Single on Purpose, Kim takes his signature no-BS “self-help in a shot glass” approach as he shares his own singlehood story and shows readers how to own their shit, break their patterns, and find a grounded sense of self.
 
　　Spending time to cultivate your relationship with yourself shouldn’t be something you only do when you hit rock bottom, go through a major loss, or have a quarter-life crisis. All of us, at some point, need to be single—on purpose.
