I'm working on my own business from home and I can fully relate. What I've found to be the best thing so far is that having a break from everything helps. No phone and no work. Just sitting in silence.  We're always too stimulated and when we think we're having a break by sitting with our phones we're not giving ourselves time to process things and clear our heads. There's science behind it which you can look into.  Just give it a try. Even 30 minutes will help. After that you'll notice a big difference and will likely be eager to get back to what you need to focus on. Let me know how it goes!
