At my team, we recently established a rule that during Friday you can work on anything work-related you want (e.g. it doesn't have to be something from the actual sprint etc). Similar to the old Google "20% for your projects" kind of a thing. I expected that lots of useful or interesting things will be made during that time, which is true. But for me, the most beneficial effect is that my enjoyment of my work (which previously wasn't bad - I really liked my work) increased a lot. So this can be another way how to boost your job enjoyment.
