Help: Building Awesome Personal Organization Systems

Related to: Rationality Power Tools

I’m looking to use (or make) something that helps me achieve god-like productivity. In particular, I’m interested in any information about systems that are:

  • Flexible: They can be extended or customized to accommodate new work-flows and a diverse range of information structures (like to-do lists, schedules, etc.), perhaps via easy coding.

  • Linked: The elements can be connected and categorized using a variety of link types (like is_an_action_for, is_a_subgoal_of, etc.).

I would prefer not to have a bunch of separate systems if possible. From what I’ve seen so far, org-mode seems the most promising.
