This is just my 2c but I don't think Medium really has very much audience. if you are going to write on a content site one like Hubpages will at least pay you. Also they are better at directing at least some of the traffic to your other material rather than stuff by random other writers. Or you could look at content sites or blog networks that specialize in wellness or selfhelp. But the fact is Google Fred (the latest algorithm) tries pretty hard to ignore anything in that subject area not posted on a single-subject authority site.

Just some thoughts, but you have only just started and choices made early on can really affect how well things go. My best guess is that in a few years Medium will no longer exist, so be sure to back up your work.
