成功不是终点，失败也非致命，重要的是继续前进的勇气。

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.

If you want to be a leader, you have to be willing to make unpopular decisions.
