I think that the main problem of a customized and changing over time curriculum is that it's hard to maintain connections to information in long term memory over time. Ever since I started using a spaced repetition/interleaving program, I find that I can start learning something, then walk away for as long as I like, and be able to come back to the subject not just fresh, but with the previous information far more entrenched than before. This allows me to jump around my interests rapidly within the limited time that I have for learning difficult subjects, and means that the time that I do spend on particularly difficult subjects that require deep understanding isn't wasted. I think that meta-learning is a key subject that any learner should start with, then messiness isn't a problem anymore. If I had learned it 20 years ago, I probably wouldn't have lost all of that wonderful college expertise.
