68. creating an Avatar is something that's not as important as it's made out be?

Question:
Hey Stefan I just finished watching the research module videos. Amazing how quickly those questions got answered in under 2 hours in different niches. I'm really excited about applying. I do have a question...You never mentioned anything about creating an Avatar is something that's not as important as it's made out be? You know writing to and knowing "that one person". What's his name? How old is he(not a range :) )? What are his goals? Etc. I supposed everyone has their methods. But When you're researching and you discover your market has different kinds of people with the same problem yet different painpoints, do you write to all of them in one sales letter?

Let me give you an example...I'm doing research on the plantar fasciitis niche. I found runners (Triathletes to be even more narrow), people whose work has them standing A LOT (i.e Nurses) and Over weight people. The Runner is upset about the problem because it's preventing him from running/preparing for a 10k. The Nurse is worried about not being able to do her job properly because of the almost unbearable pain. You get the point. Their Victories and Failures for example are completely different even though it's the same problem. What do you do in this case? Hope my question is clear...
