I have never understood the topic about work-life balance. Why is it about working and non-working cases, why should I divide it like that? You can balance all the work in general, well, or divide them according to another principle. For example, «I need» and «I want».
Then try to shift everything important to «I want». Look at this work from a different angle; try to find a hidden interest or motivation. And if it doesn’t work out — figure out how to stop doing it at all.
