The positioning line: who you help, with what, in which format
Plenty of would-be creators stall in week two because every morning they have to decide all over again what to talk about. The real gap is a niche that was never put into words. The most useful first exercise is a single positioning line: "I help [who] achieve [what] through [which format]." For example, "I help students in shared housing cook three meals a day on a tight budget through short videos," or "I help office workers handle English in meetings through weekly carousels."
Then the line gets tested. Learners list twenty questions people often ask about their topic. If that list fills up easily, the topic holds months of material. If it runs dry around line seven, the angle may be too narrow, or the interest may not be strong enough yet. The second test is the fifty-piece question: could they cover this theme fifty times and still enjoy it?
Next comes a distinctive angle. Learners open three to five accounts in the same niche, note which topics are already crowded, and mark the gaps that hardly anyone touches. An angle can grow out of a point of view (budget cooking for students living away from home), a personal background (a teacher explaining school lessons) or a delivery style (calm and step by step). Once the line has settled, it works as a compass whenever the idea bank feels empty.
If you can write twenty audience questions in one sitting, the niche is ready to steer your content.
