Bullet Journal is good, I can also recommend "Getting Things Done" (but don't take everything seriously though) and any book on the Pomodoro technique.
Right now I'm reading
- Designing Your New Work Life which seems interesting (science-backed philosophy on why work sucks and how to love it, it's a fun book so far), and
- the latest version of Discrete Mathematics with Applications for computer sciences (the latest version).
BTW, why are we using librarything instead of goodreads? It's the first time I've seen this web site.
