2. Map Ideas.
Start mapping out your ideas on paper. Write down an idea on your paper and circle it. Then draw branches (like sun rays) off the main circle and write down ideas that correspond or complement the main idea. You can do this several times, filling a paper with several main circles and branches off the circles.
3. Look at your ideas and choose. Take a look at the ideas you have written and choose the one that sticks out the most to you.
4. Consider your resources.
You will probably have to do at least some research. If you need information, check out some web sites or print media before you commit to your topic.

It is important that you don't procrastinate when writing a speech. If you keep pushing the work until the last possible moment, you won't end up with a very good speech. Speech writing is an art. It takes time to brainstorm ideas, research, write, edit, and practice a great speech. If you need help with this process, seek out a good speech coach to help you, advise you, encourage you, and guide you. Don't wait. Do it now.
