Been at my current job 9 years, been coding professionally for ~33, and 43 years total. I occasionally work (code) a 10 hour day if it's a project I'm really into. Most of the time it's 8 hours of "availability" - I spend my mornings online on a laptop in my living room, but still waking up. I work from home, so 9am is my usual wake-up as well as arrive-at-work time. If things are really going haywire when I wake up I'll go into my home office and start working. I rarely have any meetings before 1pm. People who schedule 9am meetings are the worst. I've spoken to my boss maybe 5 times in the last 6 years, he lets me do what I do leading my team, so it's pretty chill. I also work on my own projects every night from ~8pm to midnight or 2am. So I'm still good to code, but I either get exhausted by, or lose interest in the day job stuff by 6 or 7pm. It's time for dinner, put on a show or a movie and work on the stuff I'm actually passionate about. I get out on the weekends or work on projects that aren't programming.
