I lose energy if I do have breakfast. Which results in lack of focus. Therefore I often postpone my breakfast as long as I possibly can, otherwise, with a large probability, my work day is ruined before it even starts.

I think this has a lot to do with the 9–5 and my natural sleep cycle being delayed compared to that.
