No surprise, no fun, much time and motivation lost while searching for something new. In a liquid, the molecules mix around. In a solid, the molecules stay linked together in an unchanging structure. To solve problems you have to think up new thoughts. A liquid memory that keeps returning different ideas allows new combinations to form.
Creativity is the re-arrangement of old ideas in new ways.
An organized mind, which keeps returning the same answers to the same questions, is not very good at thinking up solutions to problems. A creative mind thinks up many new ideas, then tests and rejects most of them and keeps the few that happen to be good. That's the only way to come up with new ideas. You can no doubt think up lots of possible solutions to problems, too. You can use your creative talents to do wonderful things, including thinking up ways to make most of your filing unnecessary, or thinking up filing systems that will work for you.
