A Fierce Practice started on Instagram in January 2015, and the Tiny Letter began in March 2015. Impossible to search, but fun to browse...two years of A Fierce Practice daily newsletter live here, in the TinyLetter archives. Get at it, but good luck finding anything specific. The easiest way to get it all in the future is to subscribe.
The archives on this website date to January 2017...but one day in the future I'll get my act together and add all the previous content.
