This study examines the use of Attitude resources in the introduction chapter of a self-improvement book named Atomic Habits through the framework of Appraisal Theory, employing both quantitative analysis of frequency and qualitative discourse interpretation. The analysis reveals that in the introduction chapter, Appreciation is the most frequent Attitude resource. Linguistics expressions of Valuation are predominantly positive, emphasizing both the book’s significance and the author’s achievements. Additionally, Quality and Composition resources underscore the book’s practicality and intellectual foundations. Affect primarily conveys negative emotions related to insecurity and unhappiness, reinforcing the author’s struggles in the early narrative. Judgement, particularly Tenacity and Capacity, highlights the author’s perseverance and growing competence, shaping his credibility. The evaluative language in this chapter constructs a compelling narrative introduction: moving from adversity to achievements, while also reinforcing the book’s authority and usefulness. Through this strategic use of Attitude resources, the introduction not only demonstrates the author’s personal journey but also establishes his credibility and highlights the book’s value, effectively engaging and persuading readers. This study reveals how self-improvement books strategically blend appraisal resources in narratives and academic writing to engage readers emotionally while establishing credibility, expanding the application of Appraisal Theory to this genre.
