Happiness is not something ready made. It comes from your own actions.

父母死气沉沉的生活对周围人特别是自己孩子的影响，是无与伦比的。

I would like to fly in space.Absolutely.That would be cool.I used to just do personally risky things， but now I’ve got kids and responsibilities， so I can’t be my own test pilot.That wouldn’t be a good idea.But I definitely want to fly as soon as it’s a sensible thing to do.

You have to believe in yourself when no one else does.
