10-20-30 Rule (not the message, just the messenger here)

As sales professionals and leaders we are often tasked with giving presentations. I strongly recommend the Guy Kawasaki 10-20-30 rule whenever you use PowerPoint (or keynote)1.) Here is a link to Guy Kawasaki’s blog that explains it: http://blog.guykawasaki.com/2005/12/the_102030_rule.html (btw this is a great blog to follow) 2.) Here is a link to a video of Guy explaining his rule (less than 2 minutes) http://www.youtube.com/watch?v=liQLdRk0ZiwWhat are other rules of thumb you have seen work well while using Powerpoint?
Keep Crushin’ it,
