Interesting concept about wealth and money that I read in paul graham’s book Hackers & Painters.
Often times we mistake wealth for money, wealth is something that people want.
You make money by getting rewarded for the wealth you have created, take an example of Jan koum and Brian Acton, a few years back they had created whatsApp and fast forward their wealth was rewarded $16 billion dollars.
So how do we differentiate between a side project and a wealth? well, your users are the proof for the wealth, you have created.
So the main take away is that you get rich by creating wealth, and you create wealth by building something people want.
