I got two things in progress… chunking material from a book I read into bullets and placing them in rooms. Its a book about psychology and I wanted to recall some interesting parts during everday life.
Also thinking about learning geography just to have a better view of where things are.
Alphabets so I can learn to read more languages.
Cities and regions in various countries because I love maps.
Vocabulary for the same reason as alphabets.
Styles of shorthand so I can scribble faster.
For a professional degree.
Mostly law for now. Will try more things as I get to study new subjects.
Passwords.
