The recent "gardening in Obsidian" post on HN has motivated me to put a bigger focus on how I take notes and how to do it more effectively. I've been unhappy with how I hold on to knowledge I want to keep long-term for a while now, but felt paralyzed by all the options available to me. I've been on a bit of a bender reading in the past week or so about note-taking and I've made some crucial insights that will have a big impact on how I proceed.
I'd say my primary goal for the year will be to transform how I offload information into my "second brain" and how I couple that with spaced repetition (through Anki).
tl;dr Learn how to take better notes.
