Advice I gan give..even if I don't follow it as well as I should:
-Ever read a Dale Carnigie book?;
-Always have a pleasant demeanor, and be first to say "Hello" or "good morning";
-Watch those who have the knack; and,
-Immigrants- even the "slowest", seem to have exceptional people skills, and manage to avoid getting caught up in job politics. Watch and learn.
