Excellent Written and Verbal Skills? Define Excellent.

In my persistant search for post-graduate employment I've ran across the word excellent quite a bit in reference to what many companies feel an ideal canidate should possess; especially pertaining to a potential employee's articulacy, which then makes me wonder if my verbal and writing skills are equivalent to that of excellence? Does my speech exude the excellence that is required to be considered excellent? Is writing an excellent job-fit for me? Will i excel at it? Will my possible lack of excellence in any particular skill overshadow my excellence in another? Does my excellence in any skill rely on my use of the word excellent to define it? Is the use of the word excellent an excellent selling point in an attempt to advertise the excellence of a particular skill? Damn it!
I wish there were an excellent way of knowing the most excellent ways in which to showcase skills in which one is excellent! Or at least, which skills one may have potential to excel at. In hindsight, this really hasn't helped, or even been cathartic, has it?...excellent.
