I'm taking off nights and weekends for the first time in a decade, solely because of the speed up of LLMs
Research has repeatedly shown that people can only be productive a certain number of hours in a week. People who work more then a healthy number of hours are probably doing busywork.
I have always taken off nights and weekends and I have built a lot of things I am proud of. I am also very happy with my career so far.
I'm in my forties now with a teenage kid and I often realize how fast life flies by and we only get one shot at it. So I'm very happy I chose to work part-time some years, so that I could spend the afternoons with our kid.
