写程序是一个循序渐进的过程，一开始都是加加减减，修修补补，这和我们做企业做创新的原理都是一样的，没有一蹴而就的成功，最近看了周鸿祎的《我的互联网方法论》蛮有启发，分享给大家几句摘抄：

2.颠覆式创新，就像自然界的新陈代谢一样，不断把老的、旧的公司从行业中挤出去。所以，这种颠覆式创新已经成为美国硅谷的一个象征。破坏和颠覆，都是强调打破原有的平衡，建立新秩序。但这两个词在中文里都是贬义词，因为中国文化崇尚平衡、稳定、和谐。一说颠覆式创新，我们的潜意识就会觉得是反动的东西，就不由自主地想到阶级敌人搞破坏。我有些时候受邀给一些单位讲互联网里的颠覆式创新。讲完后，有的领导就过来跟我握手说：小周，讲得挺好的嘛，只不过以后不要讲颠覆、讲破坏，影响社会和谐。

3.我不赞成企业大张旗鼓地搞创新，非要巨额投入资金，非要设立创新研究院，非要做一个整套的创新战略。我觉得休克式疗法的创新很难成功，我主张把创新从神坛上拉下来，从一些细微点上进行持续创新，这样反而更有效。

4.乔布斯有一天给谷歌高管打电话，说苹果iOS有一个谷歌地图图标，放大多少倍之后，第三行一个像素颜色不对，他认为这影响了iOS的美观。这就是对细节的一种坚持。
