Entrepreneurship is a crusade. Entrepreneurship is something that you do to come to a meaning in life. You do not become an entrepreneur so that you may sell-off your venture after four years and then move to something else to make more profits, to consume and fatten your belly.
Entrepreneurship has to be a love affair, a lifelong love affair. Entrepreneurship must be something that you can persist with even if you do not make any profits. Only then, obviously, it can be lifelong. Otherwise, at some stage, you will give in.
You are a good entrepreneur, you are a worthy entrepreneur if you look to make money so that the firm can keep going and keep expanding. And you are not a worthy entrepreneur if you are looking to make money so that you can consume more and more.
