Niche perspective

Brooke is insistent that we identify a niche by identifying a target market going at least three to five levels deep. We usually state this in terms of demographics such as male/female, age, etc. Can a niche be identified instead by focusing on a specific area, e.g., not male or female but anyone who wants to solve a particular problem such as discover their life purpose or find a career, etc.? Is that still too broad an approach?
