I posted this before, but it feels like it’s time to do it again.
The video is from Ted.com. It’s worth checking out.
Here are a few others that I like. The first is from Malcolm Gladwell (if you aren’t familiar with his books, you should be). The next talk is from Seth Godin, who talks about standing out. Last is Tony Robbins (I know, I know), speaking about why we do what we do.
