If the books are cluttered and disorganized, it will be difficult for the person to hold onto them and they may end up dropping the entire stack. However, if the books are neatly arranged and organized, it will be much easier for the person to hold onto the stack and carry it without dropping anything.

In the same way, a simple and well-organized design or solution is often easier to understand and work with than a complex and convoluted one.
