A few years ago, I started having an experience like "I'm finally learning the things I knew when I was 17." (I'm 55 now; no implication that it takes decades, lol.)
It's natural to have beginner's mind when everything is a literally new experience, and you're "learning". Now, beginner's mind is still natural (see
soulsings' answer), but a "learner" part of you will be participating in that, in new way after new way. That may seem like you're "learning more" (see
qweilun's answer), or it may not require learning at all.
For those of us who came to Buddhist thinking thru New Age thinking, this is one of the places in New Age thinking, where it's easy to get stuck: thinking that it will always be spiritual "evolution", self "development" (whatever the self is ;) and "learning principles"... all of which has value, but if we "identify" with this "forever learner", it automates itself, and can be experienced as unstoppable, even as a burden...
Whereas another thing I've noticed recently: that my most touching "lessons" are not "learning"... less and less "new information"... more and more "old information freshly present."
Somewhat aside, but that you might enjoy considering: Gangaji, (a Zen Buddhist who became a student of Papaji), sometimes says things like this, that have a beginner's mind flavor, for me:
"What is at peace, what is already free, what is endless in its realization of itself, is here now, and is who you are."
In that context, there is the endless, which will never provide a "place to land", and the already here, which does not require a "place to land."
