Not everyone is going to be interviewing at Goodby, Wieden, Fallon or Crispin.
If you are, don't consider that a success. Blasphemous as it sounds, those agencies have turned out some bad work, too. (And they usually put the juniors on those assignments.)
If you're not, don't consider that a failure. There are a lot of unsung, unheralded and undiscovered agencies who are just waiting for fresh talent to take them to the next level.
