If everything went as planned, remember you were just lucky. Because some terrible emergency could have cropped up that might have jeopardized the entire program. Your meeting planner checklist could have got torn or could have got lost taking with it the vendors and contractors receipts and other important documents and papers. Besides, if you were the only expert planning the meeting, a lot would depend on you. If you slipped up or failed, the whole event would collapse like a house of cards.
