Be specific and make sure to include a time estimate for all tasks. A well-maintained list is an essential tool for staying grounded, for saving your energy and for doing things rather than trying to remember what to do.
要具体，并且确保对你所有的任务都进行时间预估。一个维护良好的任务清单是脚踏实地办事的必要条件。这样你能为做事节约精力，而不是总要试着去记住要做些什么。

Effective to-do lists are limited to specific tasks that can be tackled right away and finished fairly soon. Instead of listing solve client issue, spend one hour defining the scope of client problem.
有效率的任务清单要局限于那些能够马上解决并且能短时间内完成的特定任务。与其列出要解决的客户问题，不如花一个小时来确定客户问题的范围。

A list should reflect a time estimate needed for each task. And it should be integrated into a calendar or schedule, to avoid planning 17 things for tomorrow which, if you added them up, are going to take 20 hours.
清单必须反映每个任务的时间预估，而且应该整合进你的日历或时间表里，以免你为明天计划总计要20小时的17件事情。
