Stalling at the Top of the Learning Curve

I like the concept of the learning curve and in the context of a conversation about learning to learn, being aware of our individual learning curve around a particular topic can be valuable.

For example, I feel as if I have reached a point on the learning curve around this theme of "learning to learn" where the returns have become minimal.  I read these types of articles (previous posts) but I've come to the point where it's really a scanning process rather than deep reading.  I'm looking for something new, a new concept, a new idea, and 90% of the time, I'm a little disappointed because it's not new (to me).  It's almost become boring.

What should/could I do about it?

1. Look at it with different lenses
It would be arrogant to think that I know everything there is to know about "learning to learn".  Let's assume for a moment that I've been looking in the wrong places for additional knowledge.  I need a new direction, a new angle.  Perhaps I should revisit another recurring interest, neuroscience, and see if there are useful connections with "learning to learn" that I have yet to explore.

2. Look away for a while
This is just a symptom of being bored with too much of the same thing.  I just need a break from "learning to learn."  I should consciously avoid the topic for a while (perhaps a year) and then get back to it with fresh eyes.  For example, my recent interest in permaculture has created a nice break from standard knowledge management and related topics which I constantly read about.
