This is a video in which Mr. Kipchoge talks about his upbringing in Kenya and his attempt to break the two hour barrier in the marathon, which he almost did last May. It’s worth watching I think (turn on Close Captioning, but listen too, as his accent makes some of the captions that are produced inaccurate).
Three important items from his talk:
1. Stick to your priorities
2. No excuses
3. Learn to say “No.”
Finally, he argues that discipline is like a muscle – the more it gets put into use, the stronger it becomes.
