I wouldn't think so-at least not for me. It all depends on the individual and his/her individual passion and interest in writing as a whole. Do you write strictly for the extra income, or do you write mainly because you love the written word? These are a few questions you have to ask yourself. If you love the craft and art of writing, than a change in CPC is not going to change your mind a whole lot. Besides if you push yourself hard enough you will be able to earn money freelancing no matter what obstacles may come your way.
