Best systems for lifelong learners: Time blocking (protect a fixed daily slot, treat it as immovable). PARA/Second Brain (tag knowledge by the project it’s relevant to). Anki for spaced repetition (15 min daily beats any re-reading). MIT Method (identify one most important learning task per day, complete it first). Weekly review (20 min: what did I complete, learn, discover as gaps?). Immediate capture (record any interesting idea or insight instantly). Start with time blocking — the other systems build on top of a protected window you actually show up to.
