More from Joan Westenberg:

"Epictetus was a freed slave who used a rented room as his classroom, where he taught philosophy and shaped an almost embarrassing amount of modern thought.

And the poor blighter did it without Obsidian, without a PKM, and without any AI agent to manage his second brain (bad luck). He didn’t even believe that capture itself was the right problem; his system started instead with a simple question.

What is yours to manage?

Epictetus focused on three things: your judgments, your desires, and your decisions; in particular, he emphasized choosing what to pursue, what to turn down, what to keep, and what to cut out completely."
