One habit that has made me a better storyteller.
At the end of the day, in an excel sheet, document one story.
“Homework for life” is what Matthew Dicks call it.
It doesn’t have to be a complete story, of course. It can be an incident that stayed with you. A small insight that you had. A joke that you liked.
Basically, anything memorable that caught your attention during the day.
Later, you can develop these ideas into stories that you can use in your talks, emails, sales pages, articles, and so on.
