While I like the idea of having multiple income streams, I don't like the word "passive" in this context. Everything you mention requires constant (or at least initial) work. If you don't post on Medium or Youtube, your earnings will drop. If you don't update your apps, they won't be used anymore.

And it appears to me that you invest a lot of time. If you like it that way, then ok. But what will you think in 10 years of your present self? Maybe you should try to enjoy life more, but that's just a hint. You need to figure it out for yourself.
