Time/week spent: 5h - 20h

Engaging in writing a book as a side hustle typically required a commitment of 5 to 15 hours per week. Initially, more time may be needed for planning, outlining, and researching, which could range from 10 to 20 hours per week. As the writing process progresses, the time spent might decrease to around 5 to 10 hours per week. Tasks involved include brainstorming, drafting, editing, and formatting the book. This side hustle can be part-time, fitting around other commitments. Online discussions suggest that many individuals spend similar amounts of time on their book projects.
