The details nobody notices are what make the whole thing feel right. Sweat them anyway.

Nobody will compliment the kerning, the two-frame trim, the chamfer on an edge. They will, however, feel the result, because quality registers as an overall impression rather than a list of noticed choices. Audiences are excellent at sensing care and poor at identifying where it is.

Pick one thing in your current project that nobody would ever point out and get it right. Then ask someone to look at the whole thing and tell you how it feels. They will not mention your detail, and the word they use about the whole will be different.
