I've experience the exact same thing. It becomes a cyclical rut of feeling like you're not making enough progress on a project, then feeling guilty for spending time enjoying other things. Thoughts like "why should I enjoy my sunday morning in the park? I could be working feature x". My advice isn't for everyone, but I got over the rut by realizing we're not going to be young and healthy forever. The term YOLO has become epitomized with young people making stupid decisions but some of us should really take it to heart. I read a piece about making life decisions based on a regret minimization framework. Essentially you ask yourself which life you'd regret least when you're 80 and that's what you should do. I asked myself whether I'd regret never launching a successful product more, or never living a fulfilling life with adventure and meaningful relationships. On a more concrete note, it's important for me to schedule time for exercise and fun. It helps by keeping me productive and my brain healthy, but also you won't have that voice in your head saying "hey, you should really be working on that other feature right now".
