1) "The 10 [knowledge I'm teaching] Every [people/niche/demographic I'm targeting] Should Know"

-- OR --

2) "10 [knowledge I'm teaching] Every [people/niche/demographic I'm targeting] Should Know"

Note: the difference is the "The" at the beginning (or lack of "The"). I think it's more powerful/authoritative WITH the "The." -- What say you?

Thanks.
