It depends on how much time I have. I take short breaks from working, for instance to walk the dog. These walks clear my mind, and I often find solutions for problems while taking a walk. In fact, when I'm stuck, I don't continue pondering on about it, I take a walk instead.
I work 4 days a week. This means I have the weekend and, in my case, the Wednesday off. I use it to spend time with my children, and common household tasks. While playing with my kids I usually get a lot of crazy, creative ideas. Could be anything. From ideas for a blog post, marketing ideas, startup ideas, ways to change the world, you name it. I write them down for future use.
About twice a year we take a big break from working. We pack up the family and go travelling for 3 weeks or so. Usually within Europe, sometimes even further. No work, no internet, nothing. Just family time. After the first week or so you tend to forget what day of the week it is, and it's a lovely feeling. I read a lot (literature classics, philosophy), draw (with paper and pencil) or tinker (like making windmills out of empty coke cans) with the kids.
I have a great work/life balance. I have a lot of free time on my hands, but I'm willing to bet that because of this free time I use my work time much, much more efficiently.
Great photos, by the way!
