Is over-planning impacting your photography?

This week's podcast focuses on something that has impacted my photography and creative practice more than once--over-planning. When I am getting ready for a big trip or photographic adventure, I do a lot of research about where, when, and what to photograph. All that research can sometimes come in handy, but other times, this results in my over-planning my time costing me some photographic opportunities. In my own process, I have found over-planning shows up and causes me some angst in five primary ways. I don't think one is worse than another, but each can cause problems. Those areas in no particular order are: over-packing too much gear getting too much information to process can't react at the moment can't respond to cool changes in the plan disappointment. These five things often show up when I over-plan and don't properly plan for my shoots. Do any of these show up in your process or do you have others not mentioned that happen when you over-plan an adventure?
