One of the reasons they exhaust me, is that it's always "one more prompt" to get a UI correct. It's often just slightly off, but it can take 5-10 mins sometimes to rework something. It has led to me working much longer hours.

I think this is in part because I am one of the software engineers that always liked building products more than writing complex software. So, I am driven by the feeling of creating something. And I want to get the feature perfect and complete. But getting from 95%->100% done can take a long time with UI work for me.

So I work much longer hours now, unfortunately.

Perhaps do the last 5% yourself?
