Tools
I've deliberately tried to embrace a simple approach to digital tools.
Hannah Arendt described the difference between a tool and a machine as a tool is made to work with the human frame and movement, whereas a machine conforms the human to it. I try to choose tools that work well for my process and that assist (but not replace)† my thinking.
I also prefer single purpose tools that do one thing exceptionally well rather than tools that try to do everything. Here are my favourites:
Bear — for writing and connecting my thinking.
Things — for keeping track of priorities and commitments.
Signal — for secure communication with friends and family.
A dedicated password manager — I genuinely don't understand how anyone gets by without one.
Roon — for listening to digital music at home.
There are other things I use, but these are the main ones that I use all day, everyday.
