I found that, as a person who (sometimes) creates things, my attitude towards other people who create things has significantly shifted. When I was younger I would just see the fault -- the typos, the narcissism, the pointlessness, the already-been-done-better-by-others -- of people's work. But after trying a bit, it sometimes (for the same reasons the OP talks about) creating anything new ends up being really hard in…
Another is to learn from the mistakes; this sometimes requires others to point them out. A lot of the issues around it comes down to ego and how one takes criticisms. One needs to learn not to take it too personal. A lot of times, the weak points of one's work is often the bit we're lazy. Of course, many times we already know very well where we're weak, and getting it pointed out repeatedly can sting.
And to make it back to the obligation to be bad, it comes down to recognizing you can always get better. In fact, the more I learn about a subject, the more I see how little I know.
