Quantity and Consistency leads to Quality.  It is very difficult to do anything with enough consistency and repetition that you don’t develop some amount of proficiency over the course of a few months.  Most of us fall guilty of not sticking with something long enough to see it through. 

I truly believe you don’t need to be good at everything, especially in prospecting.  Show me someone who does a little FSBO, a little expired, a little door knocking, a little updesk, a little of this and a little of that and I will show you someone who is getting mediocre results.  There are only a few productive prospecting avenues (vs marketing where the field is almost limitless).  Find one that works for your personality and do it with enough consistency and quantity and you will soon find yourself excelling and becoming the panel speaker for the subject.
