How do you become a master storyteller?

If you regularly look at American late night talk shows, you might have noticed the hilarious story that Nicole Kidman told Jimmy Kimmel that you think you heard told by P. Diddy, last year to Conan O'Brien. And you might be right because it is the same story. They have people for that, publicists, writers, people who listen, remember, copy, change a little detail or nothing and then again use. If you don't employ those people, you will have to do it yourself. But it's not a tedious job at all to search, remember, register and keep track of what you yourself - or someone else - has experienced and what is worth telling. There are also institutionalized sources where you can find this, such as Wikipedia, news calendars and americanrhetoric.com.
