Is it wrong to start a startup just for the money?
If the only reason you’re starting a business is to get rich, then you’ll likely fail.
However, if you’re not interested at all in attaining at least one purely selfish goal (like money, power, recognition, etc.), you’ll also likely fail.
That’s the paradox: you need to both believe in your vision and also have a few selfish goals. If you create something great that benefits the world, you deserve some selfish gain and it is ok to want it and crave for it — that inner “want” will propel you to be a better creator, a better entrepreneur, and a better leader.
