How to be a Great Leader and Speaker

Recent research suggests that leadership qualities of country leaders are in DNA. How does this affect you?
1Bright people include INTJs (Meyers Briggs personality type), introvert scientists who want to solve their own problems, not those of other people. Einstein was invited to be head of a government but turned it down. (You might get the opportunity to be a leader but turn it down.)
2 You can lead from necessity but retire when the need's gone. The Bielski brothers from a Belarus village led about a thousand people to survive in woodlands in WWII but went back to ordinary, anonymous jobs such as being a New York taxi driver. (You have the potential in a crisis.)
3 Some people are self-propelled. Svengalis, mentors and managers push and pull pop stars, singers and royalty - Diana started as a shy teenager.
4 If you want help and guidance you can get it. Toastmasters International, motto 'Where leaders are made', takes those who are shy or scared of giving presentations and makes them competent, confident performers giving presentations on stage.
