Dan Duncan, who is a billionaire, understands the importance of patience (especially in creating lots of wealth). An example of this is his latest deal; that is, his company, Enterprise Products Partners LP (NYSE: EPD), has been pursuing Teppco Partners LP (NYSE: TPP) since March. At that time, Duncan offered about $2.8 billion for the company. And yes, according to the senior management at Teppco, it was too low.

Well, after some wrangling, there is now a deal. Of course, the price tag is higher -- at $3.3 billion (it's a stock-for-stock swap).
