I find entrepreneurs are like gamblers. Consider Bob Voulgaris:
He bet his entire life savings ($70,000) on a 6.5-1 bet that would take over six months to decide. Then he waited. Six months later, after many nights of eating ramen noodles, many days of slinging luggage, and a 15 point deficit in the 4th quarter of game 7 against Portland, the Lakers were crowned NBA champions, and Haralabos Voulgaris had a half a million dollars.
I would never be comfortable betting my life savings on anything. Even my own skills and ideas. Some people can do it repeatedly on things that are further and further from their control or ability to analyze. I don’t think it’s a virtue or disability, it’s just different.
