At some point, if you give enough PowerPoint presentations, someone is going to try to talk you into using builds. That's when you have a screen. And instead of a whole nother screen, a whole nother slide coming up. Another piece is built on the existing page. And the problem, unfortunately, is that people think, Oh, this is great. I don't have to remember anything or practice anything.
I'll just hit the button, and the next line of text will come up. And I can sort of boop, boop, boop, boop. No friends, this is an awful way of using PowerPoint. If there's something important enough for you to add it to a screen with a build, then give it its own entire slide. Preferably without using text, preferably using an image, a picture a graph. Because what happens in a lot of situations, especially when you get behind in time, you're hurrying, all of a sudden, you're like one of those birds at the checkout counters at a gas station bobbing up and down.
You're hitting Enter so often to get that next thing that texts that next thing, text. It's distracting. It's not interesting. It's boring. And you know what people can read at home, they didn't need to come here. You speak for that.
So, my advice, do not use bills. The only exception is if there's something truly visual, you're showing architectural drawings and you want to show here's what the ground floor looks like. Now, here's what the second floor will look like on top and how you can look at if it's truly something visual and layers fine. If it's just a way for you to throw up a bunch of text and use the poor man's teleprompter. Don't use builds
