My younger child, a college sophomore, sent me the following text: “I was just at a lecture that was done quite poorly. It went against everything you say a good presentation is supposed to be.” Wow, I thought. That’s pretty cool. Something I said stuck. I asked what I said a good presentation should be. “You know what you are saying and not just reading from a paper. And you don’t have tons of words on your slides.” This one is ready for the world.
