I do it by breaking up my work into chunks. Being remote allows me the leverage that isolation to give myself blocks of 100% productivity; I intersperse that with going out and doing things.

I often work outdoors in the warmer months. I've got an office at home, but I've also got a handful of places where I can park my Jeep and either hang my hammock or pull out the back seat and work in the shade, with the background noise of nature and/or traffic depending on my mood. I'll do that for 2-4 hours, then go grab a coffee or go to the park with my kids (we homeschool). After a couple of hours of that, I usually go back to one of my spots and do it again. Other days I'll work at night after my wife and kids are in bed.
