Books, classroom lectures, videos — non-interactive learning methods that results in 80-95% of information going in one ear and leaking out the other.
The point here is that instead of forcing our brains on how to remember more information with “passive” methods, we should focus our time, energy, and resources on “participatory” methods that have proven to deliver more effective results, in less time.
This means that:
- If you want to learn how to speak a foreign language, you should focus on speaking with native speakers and gain immediate feedback (instead of mobile apps)
- If you want to get in shape, you should work with a personal fitness trainer (instead of watching Youtube workout videos)
- If you want to learn a new instrument, hire a local music teacher in your city
