TJ Walker argues the old "tell them three times" rule doesn't work if the content is boring. Instead, speak in the present tense, deliver one idea at a time, and make each one interesting with stories and strong images so audiences can actually see and feel what you're saying.

T.J. i've heard the advice that when you're giving a presentation you should tell them what you're going to tell them. Tell them. Tell them what you told them. Is that good advice? My answer is no. It's frankly awful advice. Here's the problem with this if you tell somebody what you're going to tell them and you tell them and you tell them what you told them but it was boring each time, they're not going to remember it. You far better off speaking in the present. Tell people one idea at a time. Make it interesting, make it memorable, make it useful. Tell a story you're using PowerPoint. Have an image that drives it home. Make your ideas come alive so that someone can see it, taste it, feel it, touch it. Much more effective than just going through this procedural tell them what you're going to tell them. Tell them. It just doesn't work.
