Jeff Goodby once told me that “new campaigns get famous in their second year.” He’s right. The first year takes fine tuning. By the second year, you’ve got it and everyone notices including awards show judges.
If you’ve got a good campaign going, don’t bail out for another job too soon. If you do, the team that picks the campaign up after you will do the second evolution, and they’ll get all the credit for your brilliant idea. Meanwhile, you’re trapped in a hack job getting a higher salary whining that you were ripped off. Well done!
