Here is a good post I found on a website at: http://www.mindtools.com/pages/article/newHTE_05htm
To do lists will help us in our daily tasks at home and at work.  In fact I use a To Do list every morning, afternoon and evening just to keep track of my daily routine.
You can use the links to the template or make your own that is customized to your daily life.

To Do Lists

The Key to Efficiency

---

Do you often feel overwhelmed by the amount of work you have to do, or do you find yourself missing deadlines? Or do you sometimes just forget to do something important, so that people have to chase you to get work done?
All of these are symptoms of not keeping a proper "To-Do List." To-Do Lists are prioritized lists of all the tasks that you need to carry out. They list everything that you have to do, with the most important tasks at the top of the list, and the least important tasks at the bottom.
By keeping a To-Do List, you make sure that your tasks are written down all in one place so you don't forget anything important. And by prioritizing tasks, you plan the order in which you'll do them, so that you can tell what needs your immediate attention, and what you can leave until later.
To-Do Lists are essential if you're going to beat work overload. When you don't use To-Do Lists effectively, you'll appear unfocused and unreliable to the people around you. When you do use them effectively, you'll be much better organized, and you'll be much more reliable. You'll experience less stress, safe in the knowledge that you haven't forgotten anything important. More than this, if you prioritize intelligently, you'll focus your time and energy on high value activities, which will mean that you're more productive, and more valuable to your team.
Keeping a properly structured and thought-out To-Do List sounds simple enough. But it can be surprising how many people fail to use To-Do Lists at all, never mind use them effectively. In fact, it's often when people start to use To-Do Lists effectively and sensibly that they make their first personal productivity breakthroughs, and start making a success of their careers.

Preparing a To-Do List

To start preparing your To-Do List, download our To-Do List template. (Writing your list down on paper or putting it into a document is the simplest and easiest way to start using To-Do Lists.) Then follow these steps:

Step 1:

Write down all of the tasks that you need to complete. If they're large tasks, break out the first action step, and write this down with the larger task. (Ideally, tasks or action steps should take no longer than 1-2 hours to complete.)

Note:
You may find it easier to compile several lists (personal, study, and workplace To-Do Lists, for example). Try different approaches and use the best for your own situation.

Step 2:

Run through these tasks allocating priorities from A (very important, or very urgent) to F (unimportant, or not at all urgent).
If too many tasks have a high priority, run through the list again and demote the less important ones. Once you have done this, rewrite the list in priority order.

Using Your To-Do Lists

To use your To-Do List, simply work your way through it in order, dealing with the A priority tasks first, then the Bs, then the Cs, and so on. As you complete tasks, tick them off or strike them through.
You can use To-Do Lists in different ways in different situations. For instance, if you're in a sales-type role, a good way to motivate yourself is to keep your To-Do List relatively short, and aim to complete it every day.
In you're in an operational role, or if tasks are large or dependent on too many other people, then it may be better to focus on a longer-term list, and "chip away" at it day-by-day.
Many people find it helpful to spend, say, 10 minutes at the end of the day, organizing tasks on their To-Do List for the next day.

Tip:
Once you're comfortable using To-Do Lists, you can start differentiating between urgency and importance. For more on this, see our article on the Urgent/Important Matrix.

Using Software

Although using a paper list is an easy way to get started using To-Do Lists, software-based approaches can be more efficient in spite of the learning curve. These can remind you of events or tasks that will soon be overdue, they can also be synchronized with your phone or email, and they can be shared with others on your team, if you're collaborating on a project.
There are many time management software programs available. At a simple level, you can use MSWord or MSExcel to manage your To-Do Lists. Some versions of Microsoft Outlook, and other email services such as Gmail, have task lists and To-Do Lists as standard features. Remember the Milk is another popular online task management tool that will sync with your smartphone, PDA, or email account. It can even show you where your To-Do List tasks are on a map. Other similar services include Todoist, Ta-Da Lists, and Toodledo.
One of the biggest advantages to using a software-based approach to manage your To-Do List is that you can update it easily. For example, instead of scratching off tasks and rewriting the list every day, software allows you to move and prioritize tasks quickly.

Tip:
All of us think, plan and work differently. A program that works well for a colleague might not work well for you simply because you learn and think in your own way. This is why it's useful to research and try several different ways of compiling your To-Do List before deciding on a single system.

Examples

To-Do Lists can help you stay on top of important projects and piles of undone tasks or decisions.
For instance, imagine you're heading a team that's working on a large, complex project. There are so many tasks to do, and so many people doing them, that staying on top of it all seems overwhelming.
You can use a To-Do List in this situation to help stay organized. You can structure your list by team member, writing out tasks and deadlines for every person on the project. Each day as you write out your own tasks that need completion, you can also check your Team To-Do List to see who's working on what, and if anything is due in that day. You can also include other tasks that you need to complete as part of your job.
Or, imagine you're in a sales role and have a long list of people who you need to talk to. You write out a list of everyone you need to call and every client you need to see, and start prioritizing.
You know that one client really keen on your product and is ready to buy, so you prioritize them with an "A" - this is a prospect that's really worth focusing on. Conversely, you know that another prospect is playing you off against several competitors, meaning that the you'll make less profit, and that there's a reasonable chance that you won't get the business. You prioritize this person with a "D". It's worth making some effort here, but you should focus most of your attention on better prospects.

Tip:
To-Do Lists are particularly useful when you have a small number of tasks that you need to complete. However, they can become cumbersome when you have too many items on them, or when you need to progress multiple projects. At this stage, it's worth starting to use Action Programs, which are more scalable versions of To-Do Lists.

Key Points:

To be well organized in the workplace, you need to be using To-Do Lists or Action Programs. By using them, you will ensure that:

• You remember to carry out all necessary tasks.
• You tackle the most important jobs first, and don't waste time on trivial tasks.
• You don't get stressed by a large number of unimportant jobs.

To draw up a Prioritized To-Do List, download our template and use it to list all of the tasks that you must carry out.
Mark the importance of the task next to it, with a priority from A (very important) to F (unimportant). Redraft the list into this order of importance. Then carry out the jobs at the top of the list first. These are the most important, most beneficial tasks to complete.

You can also use software-based approaches to manage your To-Do List. You can often access these from anywhere, and they can often be synced with your Smartphone or PDA.
