Remember that a pitch can take months. Remember that there will be torturous twists and turns. Resolve to roll with it for the duration. Rarely does a single day, a single action, or a single mistake define the outcome.
Much of what seems important will fall away as your presentation takes shape. The ideas you hold so dear will seem lame in a week or a month, as the agency’s strategy unfolds. Don’t fall on your sword too soon.
Engage in the battle but be be wise and patient. And try to be nice.
