孫越從演藝生涯獲得許多肯定的顛峰，於1989年轉而為社會服務的終身義工，轉變不可謂不大，其卻能甘之如飴，且盡所能獻身於傳播福音及公益活動。特別是擔任董氏基金會菸害防制志工，自己以身作則先戒菸，再全力推動菸害防制工作至今。他並經常演講分享公益心得，教人尊重生命。建國一百年時，國家肯定他對社會的卓越貢獻，總統特別頒贈景星勳章。本文採用文獻分析法，蒐集整理孫越先生相關文獻資料（以2012年董氏基金會出版，葉雅馨女士編輯之「隨心所欲－享受精釆人生」為主），再以習慣領域理論架構解析，期使世人更加瞭解孫越先生的生命歷程及其對社會的貢獻；從而知其豐富之習慣領域，進而學習成長。

Sun Yue got a lot of affirmation from the peak of his career. He became a lifelong volunteer for social services in 1989. Although the change was quite substantial, he enjoys it and dedicates himself to preaching the gospel and doing public service activities. Especially, he has been a tobacco control volunteer for the John Tung Foundation. He set an example by quitting smoking, and he has promoted tobacco control until now. He often gives speeches to share his experience about public services and teaches people to respect life. During the 100-year national anniversary, the nation recognized his outstanding contribution to the society, and the President awarded him the King Star Medal. This article collects and analyzes the literature about Mr. Sun Yue(based on the book “Free heart-enjoy the splendar life＂ edited by Miss Ye Yaxin, published by the John Tung Foundation in 2012). This article also uses the theory of habitual domains to let people have a deeper understanding about Mr. Sun Yue's life experience and his contribution to the society.
