“Use only that which works, and take it from any place you can find it.”

About this quote
Cut through ideology and ego — measure ideas by results, not origin. Learn from anyone, test fast, and keep only what helps you improve. Be relentless about removing noise and doubling down on what delivers real progress.
When to use it
- In the gym, stop copying a single program; keep the exercises that actually improve your strength and drop the rest.
- At work, borrow a process from another team if it speeds things up — results matter more than pride.
- When learning a skill, try many methods, keep what helps you learn faster, and discard what wastes time.
- If a mentor from a different field has a useful habit, adopt it and adapt it to your needs without overthinking origins.
