The world is full of people who will tell you what you can't do. What you must do is find the ones who will tell you what you can.

Success is not about how much money you make, it’s about the difference you make in people’s lives.

The only way to get good at something is to fail at it a lot.

The most effective leaders are those who lead by example.

只有服从自然，才能控制自然。
