I like to learn stuff. There is an endless amount of university content you can access online for free. It's brilliant.

Or sometimes something random strikes me like the last month I've been pretty obsessed about pencils and have been learning all about their history, their role in history, making them and just all sorts of things. I actually started writing a screenplay based on pencil related history, although it is part fact part fiction lol.

I like thinking about and researching the meaning of songs or quotes or poetry. I like researching about the person/s behind them too and how their world view might have developped. I like trying to alter or build on quotes to be more reflective of my worldview, I like penning my own sound bites too. And speeches, I enjoy writing speeches even if they'll only ever be for me. I find it really helps to write how I would express myself to others to organize my feelings and reasons and shed light on any glaring holes and such to work through.

Things like TED talks and documentaries too. I basically spend my free time thinking or doing things to help organise my thoughts (writing or art usually) or watching/reading/listening stuff to inspire thought.
