I know I will feel differently when teaching and research deadlines start to overlap and the stress compounds, but the experience of the last few days makes me think I had so little energy lately because I had too little to do. There is something very different between having a solitary (but supervised) project where you are always meant to be getting as much done as possible and the social need to be present when expected by others, teach, answer questions, grade, and so on. Even non-academic obligations like recording a recent podcast have cost me standard hours of sleep but added rather than subtracted energy.
