How do you measure successful entrepreneurship? A tricky question!. I think profitability is not everything. There are a few other metrics that I believe are crucial for entrepreneurial success, and the most important among them is learning: loss could be around, if you fail to learn. Success and learning are indispensable to each other, and the latter is a continuous and unending process parallel to the changing world. So, while reflecting and evaluating your progress, ask yourself how much you have learned. Having said this, I don't deny the importance of other key metrics. Revenue, client base, response to marketing efforts, customer satisfaction -- all these things matter, but don't put aside learning, which is a key determinant of success in entrepreneurship . . . and also undeniably in life.
