A few months ago, I highlighted a book passage about finding what you want by starting with what you don’t want. 

You can similarly find good ideas by looking at the things that upset you, and then making something as a response. “I keep thinking that I shall have no more to say – and then finding some wonderfully idiotic doctrine which I can contradict—a negative approach, as they say, but one that doesnÍt seem to run out,” says Mary Midgley. 

I came across the quote from Austin Kleon, who has also identified an annoyance with each of his books:

Pay attention to what makes you grumpy. Inspiration comes in all forms.

P.S., When it’s time to promote your work, you’ll have a much more interesting and probably impactful time.
