CH2 Trigger
Summary
1Habits are not created, they are built upon(eg:habits like pearls)
trigger分为内外两种
2. External trigger: paid triggers (ad), Earned triggers(点击量，下载量前排)，relationship triggers(介绍给朋友)Owned triggers(发送通知和小红点)
外部引导只是第一步，目的是让人逐渐形成习惯，这就需要internal trigger
3. Internal trigger: emotions, especially negative ones(eg:Yin use instagram when she fear a special moment will lost forever)
We use products to find solutions to problems.(the pain they seek to solve) 所以这些产品设计者就是在找我们的弱点，比如孤独，那就用facenook，微信，各种发状态，各种留言。
P56 Instagram让我们习惯的过程，根本原因：It is the fear of losing a special moment that instigates a pang of stress.
我们为什么发短信？为什么看电视？这些习惯帮我们解决了什么？同样，如果想戒掉这些瘾，我们可以问问自己，我为什么要玩微信？我是从来没有想过这个问题。需要和他人联系，那为什隔五分钟就想看？我是怕错过什么吗？对我来说其实更多的是把他当作一种放松，和工作学习相比。那么我是否可以找到其他放松的替换方式呢？
4.内外trigger的关系
New habits are sparked by external triggers, but associations with internal triggers are what keeps users hooked.
To build a habits forming products, makers need to understand which users emotions may be tied to internal triggers and know how to leverage external triggers to drive the users to action.
