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