Too often, I realise how little I know about this world. I am not talking about details, I am talking about the big picture. The kind of things you would expect to cover on an Earth 101 course in an alien university. So, I look for reasonably well sourced data and visualise them hoping to aid my perspective on life on Earth.
I read books and then I forget about them. So I take notes. But then I never go through the notes again. So I am trying to find nicer ways to revisit notes and themes from books in a more engaging and non linear way.
