Timeless wisdom you can translate into disciplined decisions
Quotes are not trading signals. Use them to improve decision quality: identify the claim, test it with evidence, and write down what would change your mind. KeepRule organizes quotes by investor and topic, then adds context so you can turn memorable lines into repeatable checklists instead of cherry-picking wisdom to justify a pre-made thesis.

47 quotesView Quotes →We prioritize source attribution (letters, books, interviews, transcripts) when available. If a quote’s provenance is unclear or widely disputed, we avoid presenting it as a verified primary-source statement. Treat every quote as a starting point for thinking—your decision should still be grounded in your own research and constraints.
No. Quotes do not include the context you need for an investment decision (valuation range, balance sheet risk, industry dynamics, time horizon). Use quotes to improve your process: define criteria, reduce behavioral errors, and create review triggers. Your trades should be based on evidence and risk limits, not inspiration.
Rewrite the quote in plain language, then extract 2–5 questions you can answer with evidence. For each question, write what would confirm it and what would invalidate it within your time window. Finally, decide what you will do next (research, wait, resize, or set a review date) and record it in a journal.
Start with the investor whose philosophy matches your constraints. Long-term and business-quality focused investors are often a good default for beginners. If you are learning risk control and cycles, start with investors known for risk discipline. The best choice is the one whose checklist changes how you research and review, not just how convincing the quote sounds.
Include the source and context whenever possible (what the investor was discussing and the time horizon). Avoid shortening quotes into misleading slogans, and don’t imply a quote is a recommendation on a specific stock. When sharing, add your own interpretation as a checklist item: what would you test, and what would change your mind?
