In her book "The Art of Preparation," Susan C. Young emphasizes that personal habits and hygiene are powerful indicators of self-perception. This notion suggests that how one takes care of themselves reflects their inner feelings and self-respect. When individuals neglect their habits or hygiene, it may signal underlying issues with self-esteem or care for their well-being.

Moreover, Young points out that these habits communicate nonverbally to the world around us. They silently convey our values, mindset, and how we wish to be perceived by others. Therefore, investing in good habits and maintaining personal hygiene not only benefits our health but also enhances our self-image and the impressions we leave on others.
