What Should Go in Your Second Brain (And What Shouldn't)
Beware the collector's fallacy: the satisfying illusion that saving something is the same as learning or doing it. Bookmarking a course feels like progress. Saving 200 articles feels productive. But a hoard you never revisit is not a second brain — it is a digital junk drawer that buries the few things that mattered.
The goal is signal, not volume. Here is the filter.
What should go in
- Things you will plausibly need again — references, specs, contacts, account details.
- Your own thinking — ideas, decisions and their reasoning, lessons learned. This is the highest-value content because it is unique to you and otherwise lost.
- Hard-won answers — fixes, how-tos, anything you would hate to re-derive.
- Time-sensitive items — deadlines, commitments, follow-ups.
- Things worth remembering about people — context that strengthens relationships.
What should stay out
- "Might be interesting someday" with no real intent — the junk-drawer filler.
- Easily re-findable public facts — you do not need to save what a two-second search returns.
- Duplicates of things you will never open — saving for the dopamine hit, not the use.
The honest test
Before saving, ask: "Future me, in a specific situation, will want this back." If you cannot picture that moment, you are collecting, not capturing.
How SuperLazy keeps signal high
Because SuperLazy summarizes everything, even when you over-capture, you are not stuck rereading walls of text — you skim the gist. And because retrieval is by asking, the few things you truly need surface to the top instead of drowning. It softens the collector's fallacy, but the discipline of capturing with intent still makes your brain sharper.
