1. Plan your study and work in advance. Make a list of your daily and weekly study and work plans, and systematically and comprehensively learn and record what you want to learn and are interested in. At the same time, prepare a to-do list. , analyze and check or consult to-do list.

2. Do what you planned that day and try your best to finish it. Remind yourself in different ways in your notebook, dormitory, mobile phone or computer, and put yourself in different positions.

3. Learn to say "no". Life is like this, full of unknowns, and plans can never keep up with the rapidity and impermanence of change. Many times, the plan is planned and there are some temporary changes. For example, friends drag us to dinner, go shopping, or other unimportant things. In this case, we must learn to refuse appropriately. Only when a person learns to say no can he truly master his freedom.

4. Establish a correct concept of time value and efficiency, and avoid the so-called "a penny for a few hours of stupid things". Sometimes it is extremely uneconomical to wait in line for half an hour or walk for a few hours in order to save one or two dollars. We treat time like managing a commodity. We must always have a concept of "cost and value", and its benefit maximization is our pursuit.
