> If you you don't have any marketable skills, learn some.
This seems like "rest of the owl" where it leaves out a ton of critical steps. Become good at marketing is a lucrative career if you are good at it. So excuse me for being jaded when "learn marketing" seems as helpful to me as "sell profitable services". Sure, but how?
The post recommends Khan Academy, Wikipedia, and Code Academy. Only Wikipedia has info on marketing, but reading it is not the same as learning how to do marketing.
