Today I'm going to talk about procrastination. Do you have such a miserable experience? Your math teacher ask you to finish 3 math problems per week and submit them before the final. But what you think is that oh I have so much time left, just take it easy and finish next week. You hold the same view every day. However, when the deadline comes, you find there are nearly 50 problems for you to finish. At that time, you finally realize you turn your homework into a disaster. And it just owes to your procrastination.
