Chau Nguyen kept a five-year diary to improve self-esteem, reduce stress, and enhance communication skills. The diary process involved documenting daily events and reflecting on thoughts, feelings, achievements, and lessons. Writing in the diary regularly became a habit, allowing Chau to look back and better understand past experiences. Chau found that the diary helped prioritize problems, engage in self-reflection, and provide constructive criticism, skills that improved communication with others. For example, after sending the wrong file to a colleague, Chau was able to identify distractions, apologize, and work to implement feedback to improve.
