You miss the moment, which is the only time in which one ever lives. The moment is the experience. It alone is Real.
Yet many prefer the simulation to the Real, where the mind modifies what was the moment, that it may feel more comfortable, more in control of it.
I do not miss the moment. In fact, as you say, we are always in the moment. But can we connect one moment to another (understanding) or do we just experience the moment now?
I'd suggest that the next step after enlightenment (where you realize all you've been taught is wrong) is understanding (where you realize much of what you've been taught is correct).
As they say:
Before knowledge, a rock is a rock and a tree is a tree
During investigation, a rock is not a rock and a tree is not a tree.
After understanding, a rock is a rock and a tree is a tree.
