The sensible thing after a burnout seems to be more mindfulness. Paying attention when something is too much and then reducing it. I personally would not divide it between work and spare time. It makes sense to me, to reduce all sources of stress. Minimalism comes to mind. Overall less critical systems, which could drag you down. You can reduce stressful problems by automating them away. So I would just start with your own problems, going step by step and focusing on low maintenance and immediate benefits. I would set very low expectations and always be aware of the risk you are taking for your health. Maybe you will get better in the future to push something to the next level. Worst case, your own life got easier.
