Profit is surplus revenue, which means money that people paid you but which you didn't spend on improving your product, paying your staff better etc.

That's why making profit is sometimes seen as greedy, because it's money that could have been reinvested in the product.

Amazon in its early expansion phase never made a profit, because every cent was reinvested. And they didn't need to pay a cent of tax for that reason.

Profit is “how much your whole is more valuable than the sum of parts it consists of”. If your taste is what makes it valuable, then more profits reflect more taste.
