My tightly-gripped two cents says this is advice we all need to keep in mind. The industry (Ogilvy fired a reported 10% yesterday, a rumored 340 people)is contracting. The economy seems to be worsening. We can't do anything about that. What we can do is work hard. Don't let fear over-take us. Don't get down. And help your friends and neighbors. In other words, be a mensch.
