Let's play with a little bit of symbolic logic. Near the end of the article the founders talk say, if your life falls apart then you can't count that as success. Well, you need a little bit of revenue for your life to not fall apart. We can distill that down to: If no revenue, then no success The contrapositive of which is: If success, then revenue Then given our previous theorem: If (Users and Hard Work) then Success. Causality is commutative, so we can just substitute our earlier result: If (Users and Hard Work) then Revenue. Thus we get Revenue in to that equation. This ought to work, at least in theory :)
