Project Management Source has a good list of tips and tricks for improving your public speaking skills. There are actually 27 items in the list, here is the intro and the first five to get you started:
Would you rather die than give a eulogy? You’re not alone. Public speaking is rated as the number one fear by over 40 percent of people in the world. Calm your nerves and capture the attention of your audience by following these effective tips and tricks.

1. Know your audience and occasion: Long before you set foot on the stage, lay the groundwork for your speech. The first step is to learn something about the audience that you will face. Prepare an address that is understood and appreciated by those listening. Consider the occasion: should you be casual or serious? 

2. Choose the right topic: Pick something you are comfortable with. If you have to speak on an unfamiliar subject, do your homework and research it thoroughly. You’ll want to be informed and able to answer questions from the audience. 

3. Don’t memorize: Being familiar with your speech is a necessity, but memorizing or reading from written material is not. It’s easy to lose your place and very difficult to get back on track after a lapse. Instead, concentrate on modulating your tone and voice to the response of your audience.

4. Personalize your speech: Pepper your material with small personal anecdotes or other stories that will hold the attention of the audience. Everyone loves a good story. Most people will relate and respond better to your speech when you combine the facts with a collection of interesting tales and examples.

5. Practice ’til you’re perfect: Practice at home in front of a mirror. Record and time yourself: do whatever it takes to become comfortable with what you have to say. Fine-tune your mannerisms and body language. Repeated trials will help make you less nervous on stage.

1) Establish Clear Goals

Answer the ‘Why am I doing what I’m doing?’ question. Aim high. Make your goal as just, as fair, and as honorable as possible. At KYOCERA our goal was to strive towards both the material and spiritual fulfillment of all employees in the company and through that serve mankind in its progress and prosperity. Keep the objective as large and as multifaceted as possible. It must moreover be something that every member of the company can believe in so that it can become everyone’s goal. In this way the company will be a unified whole.

2) Establish Specific Targets

By ‘target’ I mean a numerical goal for the company to aim for. It has to be a specific objective, such as, ’so many years from now we want our sales to be this much and our profits to be this high.’ You must have this kind of clear, specific target. You must make it your target and want to attain it with your whole heart and it must definitely be reached.

‘Someday we will definitely be the biggest company in all of Kyoto. Once we are the biggest in Kyoto we will become the biggest ceramics company in Japan. After we have become the biggest in Japan, we’ll become the biggest in the world. This is our target - no matter what!’

3) Work Harder Than Anybody Else

‘Work steadily, one step at a time, on the basic business; maintain unceasing diligence.’ All great things are only achieved by taking one small step at a time and doing this over and over again. Although many of you might think this is obvious, few people can actually achieve it. Nothing great ever came from mere talent and efficiency. What it takes is real work. They say there is no genius that can defeat hard work - and this is absolutely right.

4) Keep Sales At A Maximum And Expenses At A Minimum

‘Count what comes in and control what goes out. Don’t seek profit; that will come later.’ Maximizing sales requires clever and original ideas. Minimizing expenses also requires clever and original ideas.

5) Pricing Is The Heart Of Management

A manager must find the price. Above all a profit producing price, that his customers will be glad to pay for the product.

6) Do Not Be Afraid To Dream

‘Have unlimited dreams so strong that they penetrate your subconscious.’

If we have something we wish to succeed in, we must think about it 24 hours a day. Then we will be thinking about the idea we need to achieve, that ambition, 24 hours a day, and before we know it, we will be moving towards its realization.

7) A Manager Must Be A Fighter

A manager must be willing to take on all comers - and be assured of victory every time. Once a manager has decided what he wants he must have the strength of will to achieve it, no matter what.

To succeed in the face of brutal competition requires both a strong determination and the competitive drive to maintain it.

8) Be Sincere And Generous

‘Have partners in business. Enjoy the work. And make sure everybody has fun.’

The greater your competitive edge the greater the kindness you need to have in your heart. The basic rule of any business is: The buyer must be happy and the seller must be happy. In addition to striving for success, you need to be decent to everyone you work with - including your customers and your employees.

9) Look Ahead With Cheerful Confidence

‘Life turns out the way you plan it in your heart.’

In addition to having the quality of being intensely ambitious and tremendously competitive, you must also have a cheerful disposition. You cannot be constantly critical or negative. A gloomy face must be avoided at all cost, and any behaviour that makes employees feel dissatisfied or unfairly treated is unacceptable. You have to keep your dreams alive in your heart and maintain a positive and acceptable attitude no matter what comes up.

10) Good Management Takes Guts

‘Cowardly behaviour is untenable.’

To make decisions that uphold these fundamental principles takes a lot of courage, because the correct decision will not always be welcomed by everyone. Making the correct decision in the face of possible unpleasantness takes real courage.

11) Be Original And Have Creative Ideas

‘Continue, without pause, to improve tomorrow more than today, and the next day more than that. ‘

Have creative and original ideas everyday. Original work does not refer only to difficult tasks such as developing high level technology. It is about continually improving your work place through innovative ideas. Making it a better place tomorrow than it was today and making it even better the following day. ‘What can I, in my place, do to correct yesterday’s errors and work more efficiently than yesterday?’

Genuine originality is not related to education or innate ability. It comes instead from constantly thinking innovatively, from never being satisfied with the current situation, and from constantly working, even unknown to everyone else, to improve things.

Many people through years of experience in project management and life in general have developed work practices and specific knowledge that would aid others in their job performance. Since the 1960s, project management has been in a state of continuous development - primarily the advances have been made through work experiences and secondarily through research of work practices. Sharing of these lessons learned and advanced practices is the key to helping others excel in project management.

One pundit claimed that experience comes from making mistakes and learning through those mistakes. Another person posted on the wall something from his grade school experiences that stated, “I learn through my mistakes, so don’t criticize me when I do so. I do not learn when I get things right.” On the other hand, there are good practices that are developed through dedicated work efforts, but perhaps not as easily identified as the mistakes.

One of my favorite quotes is attributed to Otto von Bismark: “Fools say they prefer to learn from experience, I, however, prefer to learn from the experience of others.” Bismark makes a very valid point that one does not and should not gain most from individual experiences, but improve through the learning from the experience of others.
