Recently I’ve had some advice as well as been at a talk on how to present information. Both came up with rules of 3. Try to get 3 points across, try to do it in 3 different ways and repetition is the key.
Might be obvious to some people but its always good to brush up on ways to present your information regardless of whether its in front of a crowd with powerpoint or in an email its good to have new tools in your toolbox.
