Mr. Marketing said something to this effect: "You're a very important person in this organization. When people call here, you're the first contact they have with us. How you treat them reflects on the company. Smile when you answer the phone, and give them your full attention."
Actually, he was giving the Golden Rule and didn't even know it. As we go to conferences, interact on blogs, in emails, critique groups, and writer loops, let's put our best foot forward. The uncertainty, doubts about our ability, nervousness about meeting editors and agents, and plain old fright affect all of us at one time or another. Sometimes the most successful writer needs a word of encouragement.
Make someone else's day, and someone will make yours. Has someone ever been especially gracious to you when you were feeling down? Care to share? :)
