As speakers, we tend to spend a lot of time thinking about the importance of public speaking and how we speak.
We try to find ways to connect with our audience and we try to be aware of anything that we are doing that might take away from our speech. However, it turns out that we also have another job that we need to be doing. We have to help out our friends and colleagues who are giving speeches. Since this is something that we have spent time trying to become better at, we are the ones who are best positioned to be able to help them to become better also.
What we need to learn to do is to help them during the three stages of their speaking.
