Many quote suggest there is no limit to income, but wait a sec! How much money do exist on earth? The answer is 40 trillion USD. But the exciting fact is this is only physical currency i.e. 8 percent of total money ( physical + digital ).

On that figure there is not more than 1.5 quadrillion USD on planet. Feeeew! That's a huge amount; but now we know we can't make more than that, in our balance sheet, in present day!
