The deal-killer entrepreneurial personality

After years participating in successful and struggling ventures, I have observed a curious, but fairly consistent pattern concerning personality traits of entrepreneurs. Some of these personality traits can put to death a new venture. Certainly these traits can stunt the promised growth of an enterprise. Paradoxically, the very traits that tend to move a person toward the realm of entrepreneur can be the same traits that may artificially dissolve a company. I use "artificially" here because these may be the only issues that are within the total control of the new venture. All other threats tend to be outside the venture, and thus, outside its control.
