Preparation is really quite easy. The following seven tips are useful when speaking to the public. Timing is everything. Know the time allotted for your presentation, then design a speech that will use 75 percent of that time. This will give you some flexibility.
Most people take longer than they planned.
And if you do end early, remember that no speaker has ever been faulted for wrapping up too soon. Take the spotlight. Place yourself in good lighting. If the lectern is not properly lighted, move it or move away from it into the light. Audiences feel more connected with a speaker when they can see his or her eyes, face and facial expressions.
