To create impact, to bring real value and to be better understood, you must go into significant detail.
How many times have you been at a conference where the speaker is telling you stuff you already know? The beauty is not in spouting things that you already believe people are familiar with. It lies in the connection between ideas and principles that you draw out between these various elements. It lies in the assumptions you make and the assumptions you question.
You cannot just say to someone, “Be exciting in your presentation”. Tell them how to be so. In your own words, based on your experiences.
You cannot just say, “Be authentic”. You have to tell them how you perceive this ought to be done.
You may believe that others will know how to be exciting or authentic. Indeed, they may. But they could just as easily learn something from what you’ve shared. If you expect that others will know what you already know, that what you seek to share is trite, then hardly a book or blog post would ever get written.
you help others see connections that perhaps they may not have seen possible;
you help make better sense of your past;
you use the power of narrative and story-telling to create something bigger than who you are;
you transcend the here and now.
