And I'm starting to believe the reason power/status corrupts is that it removes it as an option for character development.

Creating mock-ups and going back and forth costs time and money.

While most of the time what I do is good enough - I am getting tired of people trying to block work until unimportant details are “discussed”.

It would not be frustrating if customers would be willing to pay for mock-up work and then for actual work but what most want is working application right away not mockup but they also want to waste time blabbing about details that would be clear in mock-up or in first version of the app.
