- Emacs (with evil mode) and org-mode. The hours gained far outweigh the hours put in (and the hours put in were fun).

- Yabai on mac for not having to think about moving windows around.

- Pomodoro (now through org-mode) for helping focus (and saving hours, in a round-about-way.)

- Removing as much advertising from my life as possible. (Ublock origin, deleting social networks when possible)
