I like this quote from a NY Times article about how a lady went from working for a management consultant, to working for venture capital, to starting her own business – successful or otherwise.
Exciting as it may be, however, the entrepreneurial life is far from easy. Stress is a regular part of the day. Money is tight. There are frequent emotional highs and lows, and the desire to succeed can become all-consuming. Underlying all of this is the knowledge that failure is the most likely outcome.
That’s the very essence of entrepreneurship – the delusional desire to succeed in the face of clear and present failure.
