Set a Deadline
In some cases, you’ll have external reasons for a deadline. Often, you’ll need to pick a somewhat arbitrary date. How about your next birthday, or a particular holiday? Tying your deadline to a calendar event can help you stay focused.

Once you’ve set a deadline, write it in your diary or on your calendar, and take it seriously. If your project involves other people, let them know the deadline – knowing that people are waiting for the finished project will help keep you on track!
设定最后期限
有时候可以根据外界条件设定最后期限，更多时候，我们都是任意选择的。比如说自己的下一个生日，某一个节日？一旦你定下了一个最后期限，写在日记或你的日历上，并严格执行。
