Notice your inner expert by listening to your audience. I noticed something about a group I was working with recently that hit me in the face, and in the heart.
After my presentation, a few came up to me to thank me and then they went into an extended description of what I did that apparently was especially meaningful to them. I was touched and I discovered a bit of what they experienced from me, my inner expert.
It reminded me to do the same when I am in the audience. A simple “Thank you” is certainly very nice. However, a “May I tell you what you did that helped me, touched me, encouraged me…?” is much, much better for the one telling and the one receiving.
