Continuing my riff on the role of passion in decision making, here's a central tension in any entrepreneurial venture you don't hear talked about much:
It demands complete emotional committment to be successful, but you're also told not to have your self-esteem / self-worth too invested in the success or failure of any venture because, after all, many key factors are outside of your control.
In other words, pour your life into the venture, but don't take it too personally if things don't work out.
While we read many stories of successful serial entrepreneurs, or entrepreneurs who've had successes and failures intertwined, we don't read much about folks who failed, failed, failed, and then succeeded. I'd love to read their stories and learn about how they at once married their early businesses but also kept a safe distance, how they at once maintained self-confidence while also welcoming the excellent motivator that is fear of failure.
