Only work four hours a day

I've been job-sharing since my wife gave birth last May. I work 4 or 5 hours Mon-Fri. My output is largely the same because of this lack of separation between work and play.

If I work in the afternoon, then while playing with my daughter in the morning I'll try to have an explicit question in the back of my mind (I'm very much an IC developer so these questions are normally technical). By the time work rolls around, the work I do for that 4 or 5 hours is often quite mechanical. And with tools like GPT-4 and copilot I'm able to be more productive than ever before at straight factory-line style production of software. Similarly, if I tee up the next question in the last 20 minutes of work, I find that by the time I wake up the next day I often have a pre-prepared answer.

I know this isn't how everyone operates, but I am very happy to go without social interaction during the work day. I have friends who love being in the office and socialising around the coffee machine throughout the day. I'm much happier working from home and compressing my working day into the fewest number of hours possible to pursue hobbies - or reading The Gruffalo as the case may be.
