A colleague of mine was a finance major and said in one of his higher level finance classes on the first day the professor asked, "Who wants to make a million dollars?". Of course, everyone raised their hands and he responded, "ok, go write a book."
Which is 100% the opposite of what most of us get told in most areas, at least in tech, because book writing will net most people only a few thousand bucks, and often takes several months.
But self-publishing? Owning everything? There seems to be more upside potential there (and yes, it's harder up front, because you have to market yourself too).
