My favourites are playing Magic: The Gathering and developing strategies to improve my productivity in every day live or my studies.
In books I find leads and principles for developing said strategies.
The book I liked best so far: Deep Work.
Regardless if it is Pen&Paper, books, TV series or video games: I love stories!
In the process I like to put myself in the position of different characters to explore alternating ways of thinking and traits.
I need to move!
If I don't my concentration and mood will wither. Furthermore it is an opportunity to shut off the mind for a while.
To me music is a playground for creativity and emotion.
I like to just listen. Though occasionally, I also enjoy trying out different steps of a music production.
