Benefit of fatigue
A creative solution sometimes calls for crazy and daring ideas. Ideas you might write off at first. When you are tired, your judgment is less good, so you are less likely to write off the ideas that come to your mind. An idea that you would disapprove of when you are fit can suddenly become an option and lead to creative excesses.
We will have our next brainstorming session at the end of the afternoon.
