Someone asked me what happiness is; I replied, not pursuing unnecessary things.

Success is not just about what you achieve, but how you achieve it.

The world has the technology - either available or well advanced in the research pipeline - to feed on a sustainable basis a population of 10 billion people.

成功不是幸福的关键。幸福是成功的关键。如果你热爱你所做的事情，你就会成功。
