In my opinion, investing money into yourself in the form of tools and learning will always yield the best ROI. But obviously, that's a lot less sexy than the hope of one day retiring because you have so much "passive income". It's just that most examples for "passive income" aren't that passive, e.g. all those people advocating SaaS and Apps as a lifestyle business.
