Demonstrate your passion

A 2003 study conducted by the Department of Neuroradiology at the University of Tübingen in Germany reinforced the idea that smiles are contagious. The same can be said for passion—an essential ingredient of any pitch.

"You must effectively communicate genuine passion and real expertise," said Bruce Bachenheimer, director of the Entrepreneurship Lab at Pace University. "Investors know that even truly great business ideas are incredibly hard to successfully execute, so you better convince them you are committed and know what you're doing if you want their money."
