Cảm Xúc Là Kẻ Thù Số Một Của Thành Công

Cảm Xúc Là Kẻ Thù Số Một Của Thành Công ("Emotion Is the Number One Enemy of Success") is a Vietnamese-market self-help book compiled from the talks, lectures, and interviews of Dr. Lê Thẩm Dương, a well-known Vietnamese business lecturer and head of the Business Administration faculty at the Banking University of Ho Chi Minh City. Rather than being written as a single continuous narrative, the book is assembled — credited in later editions to journalist Nguyễn Tuấn Anh as the writer who shaped Dương's spoken material into book form — from material Dương delivered across numerous public talks and media appearances aimed primarily at a young adult audience.

The book's central thesis, reflected directly in its title, is that emotional volatility, more than lack of skill or opportunity, is what most often derails people on the path to success — whether that shows up as impatience, defensiveness, romantic decision-making driven by comparison and insecurity, or an inability to separate feeling from judgment in professional and financial decisions. Dương's material draws heavily on concrete, often provocative real-life framings rather than abstract theory; one widely referenced example reframes unemployment not as a personal failure but as, in his words, a natural and even healthy signal of a functioning market economy, intended to reduce the emotional weight readers attach to job loss.

Because the book compiles talks delivered over time rather than being written sequentially as chapters, its structure is looser and more thematic than a typical single-author business book — reader reviews describe it as somewhat disjointed between individual pieces of advice, even as they credit the overall collection with genuine practical value. Successive editions of the book (2016 through a 2021 revised edition) have varied somewhat in exactly which talks and topics are included, with the 2021 edition specifically adding expanded material on personal financial management, reflecting Dương's growing emphasis on that topic in his more recent public talks. A separate sequel, Cảm Xúc Là Kẻ Thù Số Một Của Thành Công 2, published in 2019, extends the same format with additional talks not included in the original.

The book's overall throughline is that emotional self-management is a learnable, practical skill rather than an innate personality trait — and that mastering it, more than any specific tactical business or life advice, is what actually separates people who achieve their goals from those who don't.
