It required stamina, minutiae detail, enormous flexibility, tireless charm and intense co-operation to satisfy world leaders, press, national delegates in multiple languages with the involvement of an enormous team. It requires a feat of endurance to work 15 hours each day for 40 days, working with crew of diverse abilities, keeping up morale, keeping on budget with last minute requirements (like having a bed built for POTUS in a bi-lateral meeting room!) and maintaining a sense of humour amid our passion for delivering a successful outcome.
