Been approached by a few friends (always better to be approached by friends instead of Jehovah's Witnesses!) who want to write more...journal more; some listen to music more. Basically they want to more more.
It’s weird...I find people come to me when they want to increase the amount of pop culture they consume...as I seem to consume a lot. I feel pretty average in my consumption...I probably read more books than most people otherwise I’m enjoying the same movies and tv and music as most folks.
(Truthfully what helps is I don’t care about any of the online-social media crap: being first to finish a Netflix tv show, make a comment on a movie trailer etc. We’re still publishing Plato and Shakespeare so everything will be around when I finally get to it. I want to enjoy what I consume not consume it for the sake of validation or some other nonsense.)
All this to say I don’t have a system per say...it’s like anything else in life. If I want to watch something I watch it. However if you want to write more or consume more music then I do have a suggestion:
You can combine habits...for example marginalia. Write notes/journal in the margins of the books you're reading...react, process even disagree with the writer/character (fiction/non-fiction is all reading; genres are only for bookstores).
Or read books on/by musicians that always prompts me going back to the music (currently reading a Jack White bio.
Never focus on productivity always appreciate quality. On that I can say...no more.
