Champion speakers use the "Then-Now-How" technique to capture their audience and build buy-in. Talk about how things were then. Then talk about how much better things are now. Give all credit for the change to how you have changed your ways because of this new process you learned. For example, "I used to struggle to speak. Now I speak flowingly and confidently. And it my transformation from cowardice to courage came about because I learned the three basics of public speaking I'm going to share with you today."
