You don’t often go to the grocery store just to buy one thing.
You don’t make a single trip to buy bread, then go back for toothpaste, then eggs, then pasta, then milk, etc. Most of us try to combine those tasks into a single trip to save time.
You’re probably thinking, “Of course! It’d be ridiculous to make several trips when you can cross everything off in a single trip.” It seems like an obvious strategy for tasks like grocery shopping, but we rarely think about using that same strategy for our export documentation.
