End your working day with some work for yourself.
For me this is working on my data products (datatasks and mind the docs and a secret one).
I try to use the last hour of work to push the products further. Either by coding, wireframing, thinking about concepts, Figma pushing (can’t call it designing), writing briefs. Anything works.
If I would not work on products. This last hour could be reserved to learn something new. Test some new tools, learn a programming language, learn about new frameworks.
