Create a mind map to help you generate ideas that you want to include in the speech. Put your central idea in the middle of the page and draw a circle around it. This central idea might be "What I Will Do on the Council" or "Why Students Should Vote for Me." Then draw lines out of the circle and write on those lines other ideas you have. Continue drawing lines off each idea until you can't think of anything more to say. Set it aside for a few minutes or even overnight.
Highlight the most important points on your mind map with a yellow marker. These are the points that you want to make sure you include in your speech. Write each of those points on an index card or a piece of scrap paper. Tape them up on a wall in front of you or pin them to a bulletin board. Move the pieces around until you have them in the order that you think you want to cover them in the speech. Leave them in front of you while you write the speech.
Find an interesting fact, short story, joke or inspirational saying that fits the theme of your speech. Use this in the beginning of your speech to get your audience's attention. Write a first line that will get everyone's attention while being a sincere and honest representation of who you are.
Tell your fellow students why they should vote for you. Focus this part of your speech on the benefits to your listeners. Why is it to their advantage to vote for you? Tell them what you will do and what you hope to accomplish. Refer to the items taped to the wall and figure out how to work those into your speech. As you put each item in the speech, take the piece of paper down from the wall or bulletin board.
Explain why you have the qualifications to deliver the benefits that you just mentioned. List some of your accomplishments and the personality traits you have that make you right for the job.
Thank your fellow students of listening and close the speech by asking them for their vote.
