&quot;Marketing is a multiplier&quot; is an interesting perspective.<p>The idea of &quot;force multipliers&quot; is one that occurs to me quite a bit - in fact, I even use that term in the linked article.<p>A problem for many freelancers, I think, is when the base number you are multiplying is &quot;zero&quot;.  This is, regrettably, something I have a great deal of experience with.  :)
