It's interesting that the OP says this:<p>> <i>When we think of entrepreneurs we stereotypically expect them to have extroverted traits.</i><p>and then near the end of the article essentially agrees that he had to learn those "extroverted traits":<p>> <i>over time I gained the confidence I needed to speak in public to large crowds, attend packed networking events, and pitch to powerful and wealthy individuals</i><p>I think most people would agree that introverts can be entrepreneurs, but there are certain "extroverted traits" that fit hand-in-glove with building a successful company, and I would say they are learned behaviours for everyone, simply at different times in life, or depending on one's role. Extroverted entrepreneurs (who are technical) also may need to learn to enjoy spending lots of time alone on code. This is no less of a learning process than the opposite.
