Quality is never an accident; it is always the result of intelligent effort.
Innovation is not about saying yes to everything. It's about saying no to all but the most crucial features.
没有完美的知识可以称为我们与生俱来的;唯有从经验中获得的知识才是真正的知识。
The easiest and noblest way is not to be crushing others,but to be improving yourselves.
