Task: 1) Ask me 5 questions about my skills, audience, budget and niche. 2) Map each fact above to an equivalent action for my niche. 3) Produce a week-by-week plan to my first dollar, with the cheapest tool for each step. 4) Flag which steps depend on advantages I may not have (audience, timing, capital). Do not assume any fact beyond the list.
