Improvement

I mean improvement or to improve, oneself. To get better at.

But I have questions here..

If improvement means taking myself from a fictional point A to point B, then does it actually mean I have traversed some kind of a physical or psychological distance.

And does improvement also mean that I may actually traverse from my fictional point B to point A, in reverse, but improved by moving back to some hypothetical position located behind.

If I do not leave my hypothetical position A, would it still count as an improvement?
