If a hobby project feels like “marching” then you’ll inevitably burn out. Break it down into shorter milestones. Get some small achievements, then take a break and do something else for a while. Don’t let it become a burden. Also, you need to be willing to quit if it no longer makes sense to continue. If you were doing a project for fun and it stopped being fun, it isn’t serving it’s purpose any more. Abandoning it could be the right choice if you get to this point.
