I would say work on a project that you want for yourself, regardless of whether or not if there is a market for it. If you're already in a well-paying job, money should not be the cause of your concerns. Work on something out of principle rather than out of profit. I find the gym helps me wind down a bit, but I have to make it a habit else I start making excuses not to go because I could be working on something productive, even though that hour or two would be no real loss, and getting pumped a bit actually improves my focus. I've been in 'grind mode' for my whole adult life (late 30s) and there's no sign of it stopping. For me I have the opposite issue: If I'm out drinking with friends for example, I enjoy myself and can wind down, but afterwards I feel like maybe it was wasted time I could've been working. I actually feel really uncomfortable about going out until my foot is out of the door, and only then can I 'switch off' for a while, but doing it often is exhausting. A day drinking is really two days wasted because the next day tends to be unproductive with the cloudy head from a hangover. Once in a while does help to clear the mind a bit.
