What potential negative outcome might arise if a career is based *solely* on passion or interest?

The daily grind might eclipse the initial joy, leading to eventually hating the activity.

While examining interests is a critical initial step in the internal audit, the text warns against the trap of pursuing a career based exclusively on initial enthusiasm or passion. The problem arises when the reality of the day-to-day tasks—the routine, sometimes tedious aspects of any job—becomes overwhelming. When the initial joy derived from the subject matter is constantly overshadowed by the mundane or difficult execution required hourly or daily, the original interest can sour, leading the individual to eventually dislike the very activity they were initially passionate about pursuing professionally.
