背景拓展：

游戏容易让人上瘾，所以如果把游戏吸引人的秘诀运用到学习和工作中，也许就会变得高效和有趣了，这就是游戏化（Gamification）这个概念的来源。两点建议：

1，明确学习和工作目标 (goal)

比如王者荣耀的目标是干掉对方的巢穴，跳一跳是获得更高的分数，在朋友圈刷存在感。同样，在学习工作中，给自己设定清晰具体的目标set a clear goal会让你找到努力的方向.

2，及时反馈（immediate feedback）：让自己清楚距离目标达成还需要多久？

游戏有迅速和视觉化的反馈机制，每个人可以迅速地知道自己努力的成果.在学习和工作中，每进行到一个阶段，也可以停下来进行复盘，反馈越及时，行动调整就越迅速，目标达成就越快。
