When public speaking, pause frequently. Pause before you say something in a new way, pause after you have said something you believe is important, and pause as a relief to let listeners absorb details.
I will hazard a prediction. When you are 80 years old, and in a quiet moment of reflection narrating for only yourself the most personal version of your life story, the telling that will be most compact and meaningful will be the series of choices you have made. In the end, we are our choices. Build yourself a great story.
