    - 入门:
        - 内容第一 (这也是做事分轻重的要求)
        - 内容质量
            - 重点突出
            - 例证生动
            - 消除歧义
        - 内容组织:层层递进
    - 进阶:输送价值观,你的价值观,就是你认为什么比什么更重要
        - why not cheat? you hurt yourself
    - 高级:“造化”,指的应该是一个人的 “融会贯通的能力” —— 有 “造化” 的人,不过是把大量其他领域里的技能、技巧、甚至手艺学来而后应用到自己的手艺之中
        - 学无止尽
