1. Make a limited edition of a booklet on countdown 100 days. Tear one every other day, in reverse order from 100 to 1.

2. There are three common study plans:

A, in days. Refine to what to do every day. You don't have to be different every day. For example, it takes N hours to attend a class every day, N hours to do a job and N hours to have fun.

B, in weeks and months. The plan specifies the tasks to be completed every week and every month. Don't elaborate, just 100 days what to do and what to accomplish every week.

C, subject to the matter. List the work to be done and the contents to be learned in 100 days, and indicate how many days and hours each item needs.
