I'm currently working 4 hours a day, usually from 10pm until 2am. I'm living in Thailand, so these hours overlap with clients in the US. I'm still productive, but I'm the only developer working on this project, so I don't think it's ideal. I think I could be about 3x more productive if I was in "startup mode" with a lot of equity. But I don't want to do that for this project, and 4 hours per day suits me very well. It can be hard to keep saying no, and hold onto my 20 hour weeks. The client keeps talking about bringing me on full-time, and I keep politely declining. But then I've been thinking about saving up to buy an apartment, or a new car, or a vacation to Europe... I might go full-time for a little while to save up for that vacation. But apart from that, I really value my free time. I spend a lot of my free time working on side projects. But I also really enjoy the freedom to read, or work on filmmaking, music, or other hobbies. Or to go for a walk, sit by a lake, watch TV, or just do nothing at all. I'm also working during the night, so it feels like I have the whole day to do whatever I want. It's sad that this article only talked about "flexibility", and didn't mention anything about shorter work weeks.
