"When users are unhappy but can’t explain exactly why, they often express that dissatisfaction as a series of tangential, trivial feature requests."

This bit resonates the most with me. I worked on a project worth little traction where we'd keep getting feature requests from the client facing team members for things that were of minor value but sometimes major effort. It grinds you down over time as you realise there's no real demand. Eldorado isn't over the next hill.

Sometimes it feels like the people giving feedback are just too eager to please you with positive feedback.
