"Less" and "fewer" seem to be one of the more difficult word pairs to get right. I don't blame people for having trouble with it; it handles certain concepts in English that do not come up often and are also not always easy to explain. In fact, I am certain that the primary reason for the troubles in remembering when to use each word is that people explain things so technically that it makes most people's brains shut off before the lesson sinks in.
So let me give you a handy trick that might help you remember it for the long haul:
I am a writer. A writer is one who writes.
By the same logic, I am also a thinker, an observer, and a puzzle solver.
I am a graduate from the State University of New York at Cortland with a degree in Professional Writing. The idea of the program is that one studies all three aspects of writing as a whole: Creative Writing, Technical Writing, and Rhetoric. The knowledge I have gained in those subjects is put to use in every aspect of my life.
The worst thing a person can be is boring. I am most interested in people who can pique my interests. An example is people who can correctly use the word 'pique'.
