As for making money, this is how our success is measured. Yes, you can do things for your soul, of for your friends, or for your family or for the society at large, but to be an entrepreneur means to accept to be judged, indeed, to judge yourself by your material success: money. It is not an easy thing to do. Money does not lie to you, does not tell you you're ok as you are now, that things will be better or that it will love you no matter what. Failure is clear to see, and so is success.
I probably needn't say it, but all this is worthless if you do not apply complete honesty to your work. Money is not an end in itself, it is the measure of your skill. To steal or cheat in any way makes it useless for this purpose.
