I really enjoyed this article. When I've been in a role where I had to make tons of decisions I would regularly visit the sandwich bar in the cafe and simply ask the person behind the counter to "make me a sandwich. I don't care what you put on it, I don't want to decide anything else today."
This probably just made me feel better.
I firmly believe in the maxim: 90% of the decisions you make don't matter so spend as little time on those as possible; focus on the 10% that do.
