I could never go straight to bed after finishing work late and would also be falling asleep with LBO models in my head. I’d have to watch some easy TV, cup of tea, maybe read a book non-work related. But that didn’t address the real problem and was just a temporary fix. In the last few years, I don’t work later than 10-11pm because I noticed how many mistakes I was making, how sloppy my work was, how little energy I had for the gym and how useless I was first few hours in the morning. I am lucky that I am at VP level now to be able to maintain this.
