It might sound a little crazy and potentially hyperbolic, but your ability to move faster than everyone else matters.
It matters because they don't have the same fears and concerns as you do and aren't carefully surveilling your agencies every move.
They are curious at best and indifferent at worst. Seeing someone new isn't going to sound as many alarm bells as you might think.
That's what I talk with Bogus Handzel, of Handzel and Associates, about as he contemplates when are where they new faces should appear.
P.S. Did you know Agency Nation University can help people find those new faces?
