Hi, I found few days ago very cool presentation given by Dan Ariely: What makes us feel good about our work? I think no explanations are needed. It is a very cool subject and has excellent experimental results. So, if you want to be a manager or lead one day, keep it in mind.
I found today that Dan is very smart and He has His own blog and a lot of His great work, advices, stories on the Internet. If you are interesting there are at http://danariely.com/ I had a lot of fun reading what He shares. Thanks Dan!
