Now, before I continue with the tips I found, ask yourself the following questions - and not just now but frequently at work. This will help you keep on the right track:

1. Is the task you're working on a top priority?
2. Is the task going to add value to your work?
3. Does your task help achieve your goals?
4. Could someone else be doing it?

Just by having these questions in mind your change in attitude will help you make the most of your time.

So here are some tips grouped in the three previously mentioned categories.

Reduce unused time:

1. Spend time planning and organising. Too often we hear "...I don't have time to organise!" when we should be thinking "...how much time do I lose each day because I'm not organised?" I highly recommend that you read the story Sue McMillin tells in her article to see how important this point is. It's the third link at the bottom of the page.

2. Use a to-do list. Spending five minutes to make a to-do list will help you work through your tasks quicker. If you combine this simple tool with other tips below you can turn it into a powerful time management system.

Do fewer things:

3. Set goals. Goals will give you a sense of direction and will help you plan and prioritize, which is the next tip.

4. Prioritize. Use Pareto's rule: 20% of the effort will provide 80% of the reward, so the key is to identify and concentrate on that 20%.

5. Reduce urgent tasks. These tasks usually have short-term consequences and you should be concentrating on those with long-term and goal-related implications.

6. Learn to say "NO". Eliminate all trivial tasks and those that don't add value to your work.

Take less time:

7. Do the right thing right. If you have done all the above you should be doing the right thing (effectiveness) now you must concentrate on being efficient.

8. Prime Time. Do the most important tasks in your prime time, i.e. your most productive time of the day. This varies from person to person.

9. Break up tedious tasks. When you avoid doing something you don't like, try breaking it up into smaller tasks. This will help you get it out of the way.

And to finish, don't forget that when motivated you work faster and better - so reward yourself for completing tasks, achieving goals or sticking to your to-do list.
