This is a really deep topic, but certainly worth asking about; if you’re working on an impactful plan, raising your productivity raises your impact.
My favorite starting points for thinking about productivity:
Productivity: A summary of what we know (LessWrong)
The book “Getting Things Done” (which is referenced in the above post, but is quite powerful on its own—the best book I’ve read about productivity, out of many)
The Complice blog and app (a bit different from “standard” productivity systems, but as a self-contained system, it works well for many people I know)
Thanks so much! I’ve been doing some stuff related to GTD, but haven’t read the whole book—will do so.
