Is there anything you can teach me in a minute that would become useful to me for the rest of my life?

Yes, a Chinese proverb:

If two men come walking down a road, each with a coin, and when they meet, they exchange the coins, each goes away with one. If two men come walking down a road, each with an idea, and when they meet, they exchange ideas, each goes away with two.

Communication is the key to everything.
