Life Lessons: What can I learn in one minute that will be useful for the rest of my life? originally appeared on Quora - the knowledge sharing network where compelling questions are answered by people with unique insights.

Answer by James Altucher, Blogger, author, social media, investor, Wall Street investor, on Quora:

Sergey Brin has a trick. When he interviews people at Google he usually knows within a few seconds whether he's going to hire them.

If he doesn't want to hire them he's still stuck in the interview. He doesn't want to waste any time.

He is always going for the one takeaway. If someone is a fireman, find out why it's better to use sand than water to put out a fire. If someone is a doctor, why does toothpaste cure a mosquito bite?

Here is what I do when I meet someone and I want that one takeaway. And this is the thing you can learn in one minute but will benefit you for the rest of your life.

Always ask the people around you, "Tell me something I don't know."

I just learned this from a friend of mine. I'm a hopelessly shy introvert. He told me to just ask that question to everyone I meet.

Tell me something I don't know.

Doctor: sleep constricts the nerve cells in the brain, allowing spinal fluid to wash away protein stuck to the nerve cells. Helping to prevent dementia and Alzheimer's.

"Tell me something I don't know."

This question is now your secret super power.

You can ask it everywhere you go. You can ask it in an elevator. You can ask it on a bus.

You can ask it the most. Because most is a must.
