Sooo... These are the things that I need to do to build a successful app?

Yes, but if you don't align well-enough with a genuine human desire/need, your brand will slowly but surely rot away. See Buzzfeed.

If by "successful" you mean unethical, manipulative, and popular, yes. I happen to define success as providing actual positive value to the world because those are my aims. If your goal is to be an asshole but not get recognized as the source of the assholery, then you now know how to succeed at doing that.
