1. Once at a WGS summit, the host asked Musk, what is the biggest challenge in your life?

2. Musk thought for more than ten seconds and replied that the biggest challenge in life is to ensure that you have a corrective feedback loop and then maintain this state, correcting errors, feedback, and cycle.

3. The biggest mistake we usually make is to hold unrealistic fantasies. You hope that something is true, but in fact it is not reality. You will selectively ignore reality just because it does not match what you hope for. This is a trap that is difficult for us to avoid.

4. I found that I have this problem myself. We should always maintain an attitude that we will always have flaws in what we do, and use this as motivation to reduce mistakes and seek critical feedback. If your friends love you, they will think about you and tell you bad things. So you have to tell them, I really want to know.

5. What often hinders our growth is that the people around us are unwilling to tell us the truth when they discover a problem, because the truth is often unpleasant to hear, and we ourselves are unable to truly reflect on ourselves and step out of our current state to examine ourselves more objectively.
