Did you choose the courses that you are currently enrolled to assist in fine tuning any particular skill set? I'm just curious what drove the decision to enroll- though I am sorry to hear that you wouldn't recommend, that alone gives me some thoughts as to a perceived lack of value- I could be wrong and please correct me if that is the case.
As for your statement "the way to make money on Medium is to say that you know how to make money on Medium".... Yes, I get the same feelig everytime I see a headline that reads something aboout "How I..... Billions.... Doing just this on Medium"..... Of course, I am exagerating a bit, but I feel like you've seen this same pattern. I've starting clicking and looking at other works and it seems like most (not all) discuss making money on Medium a lot.... Again, I don't have anything agains anyone that chooses to write about this topic, if it is working and helping someone to make ends meet, by all means- do it! However, I do think that long term earning potential comes from more divers content. Just my thoughts....
