Q. 1. Your neighbour always complains that she cannot finish her work in time. What are your suggestions to her?

Ans: Plan your time: Scheduling is the process by which you look at the time available to you, and plan how you will use it to achieve the goals you have identified. By using a schedule properly, you can:

• Understand what you can realistically achieve with your time.

• Plan to make the best use of the time available.

• Leave enough time for things you absolutely must do.

• Preserve contingency time to handle ‘the unexpected’.

A well thought-through schedule allows you to manage your commitments, while still leaving you time to do the things that are important to you.

Scheduling is then a five-step process:

1. Identify the time you have available.

2. Block in the essential tasks you must carry out to succeed in your job.

3. Schedule in high priority urgent tasks and vital “house-keeping” activities. 

4. Block in appropriate contingency time to handle unpredictable interruptions.

5. In the time that remains, schedule the activities that address your priorities and personal goals.

Q. 2. List the steps involved in making a time plan.

Ans: Steps in time plan:

1. Plan: Managing time involves both making plans and carrying them out. A time plan shows what one expects to do in a given period of time such as a morning or an afternoon.

2. Arrange: It also indicates the sequence of the various activities and the time allowed for each one. 

3. Plan time saving combinations of activities if possible. 

4. Allow sufficient time to do each task satisfactorily and easily.

5. Plan some time for personal recreational activities as well as for family group activities.

6. Distribute tasks so that each member of the family will carry a fair share of responsibility. 

7. Make the plan flexible enough so that it can be adjusted to meet emergencies, unexpected interruptions or shift in daily or weekly plans.

Q. 3. State the various measures one can take to simplify work.

Ans: Work simplification is about completing a task in the most effective way, using the least amount of energy and the shortest possible time. Learn to limit the steps in a job, or even whole jobs that are not essential. Determine exactly what is necessary by asking:

• Why is this necessary?

• Is it worth the expenditure of energy? 

• What if the task was not done?


• Soak dishes to eliminate the need to scrub.

• Allow dishes to air dry.

• Use a quilt and fitted sheets to make beds. Iron selectively – towels and sheets do not need to be ironed.

Q. 4. Identify the different types of fatigue. Suggest some measures to overcome them.

Ans: Two types of fatigue are:

1. Physical fatigue: It is the inability to continue functioning at the level of one’s normal abilities. Physical fatigue or muscle weakness (or “lack of strength”) is a direct term for the inability to exert force with one’s muscles to the degree that would be expected given the individual’s general physical fitness.

2. Mental fatigue: In addition to physical fatigue also includes mental fatigue. Such a mental fatigue shows itself both in decreased wakefulness or just as a general decrease of attention.

Steps or Measures to overcome fatigue: 

1. Determine what is causing fatigue by asking yourself:

• do you sleep late and wake up early?

• do you eat right?

• are you depressed or sad?

• are you doing too much in one day?

• do you have too many things going on in your life? Too much stress? 

2. If it is a matter of fixing your daily schedule/routine by having three healthy meals a day or sleeping earlier or exercising, then:

• try following a desired schedule for a week and see what results come from it.

• if you don’t feel as tired, keep up with the schedule and begin adding one more change either per week or per month.

3. However, if things don’t change, ask yourself when you feel most tired.

4. Are you generally happy, but just tired or are you sad as well?

• If it is sadness, talk to a friend or family member who you can trust and are close to. This will help you maybe see a different way of looking at things or give you ideas on how to become happy again.

• If it is depression, then you should talk to a professional who might be able to suggest some changes or give you medicine to help you.


• Change does not happen immediately. 

• Take it slowly.

• Don’t try to fit too many changes at the same time. The change might not happen immediately and it will discourage you.

• Ask a friend to help you with your changes. Join a gym with a friend, do something active with others, join a club.

• Share your feelings with someone close to you or start writing in a diary.
