How to manage your time

Does it seem like you never have enough time and wonder where all your time goes? Do you know someone who usually gets work done before it is due? Maybe they use their time well. You can learn how to spend your time wisely, too. These steps may help you find that you have more time than you think!

   1 

Write down major due dates on your calendar. Estimate how long it will take to do each project. Allow yourself more time than you think you will really need.

Make a master schedule which should include the following activities.

— all required school activities

— work schedule

— after-school activities

— blank spaces for unknown activities

A master schedule can help you keep track of all the things that you need to do during the semester. If you know what you have to do and when you need to do it, you can prepare better to meet the deadlines.

   2 

Plan when to do all your tasks for the week. Schedule time to study for tests, read your textbooks, write papers, go to work, be at meetings. Leave enough time for your chores(零星琐事)and household duties.

  3 

Make a “to do” list the night before or the first thing in the morning. If you write down what you need to do, your mind will be free to study. You won’t worry and spend time thinking about what you have to do next.

   4 

Use it for a few weeks, then ask yourself some questions. Are you getting your schoolwork done on time? Are you getting more things done? Do you feel you have control of your time?

Yes? Then your new schedule is working well.

No? Then you should look at your schedule to see how it can be improved.

   5 

Even a well-planned schedule can’t help if you don’t follow it.

It is very important to manage your time wisely.

As you get older, you will have more responsibilities. You will find it easier to succeed if you learn to manage your time well.

A.See how well your new schedule works.

B.Plan by the week.

C.Cut out wasted time.

D.Follow your schedule closely.E. Plan by the semester.

F. Plan each day.

G. Learn how to save your time.
