Innovation is not about saying yes to everything. It's about saying no to all but the most crucial features.
创新不是对每件事都说“是”,而是对所有非关键特性说“不”。
The greatest obstacle to being heroic is the doubt whether one may not be going to prove one's self a fool; the truest heroism is to resist the doubt; and the profoundest wisdom, to know when it ought to be resisted, and when it be obeyed.
永远不要低估一个执行得当的简单想法的力量。
