■ 电你是否有这样经历，当你在做某一项工作和学习的时候，脑子里经常会蹦出各种不同的需求。比如你想安心下来看 2 小时的书，大脑会蹦出口渴想喝水，然后喝水的时候自然的打开电视。。。。。。，一个小时过去了，可能书还没看 2 页。很多时候甚至你自己都没有意思到，你的大脑不停地超控你的注意力，你就这么轻易的被你的大脑所左右。你已经不知不觉地变成了大脑的奴隶。尽管你在用它思考，但是你要明白你不应该隶属于你的大脑，而应该是你拥有你的大脑，并且应该是你可以控制你的大脑才对。一切从你意识到你可以控制你的大脑的时候，会改变你的很多东西。比如控制你的情绪，无论身处何种境地，都要明白自己所面临的痛苦并没有自己所感受的那么强烈，我们当前再痛苦，在目前这个阶段自己也不是最痛苦的人，尝试着运用心智将注意力转移到其他的地方，痛苦就会自动消失，在你重新注意到它的时候，它不会回来。
