Principles of isolated pawns, particularly the IQP. - Chess Forums

Long ago, and so so far away, I was taught a rule about the isolated pawn. It went something like this: the isolated pawn, especially the IQP is a liability early on, but if you can keep it alive it can become a strength in the endgame. Therefore…? If you own it, trade down pieces so to arrive at the end game as quickly as possible. Conversely, if your opponent owns the IQP, you should avoid trade-offs because it keeps the pawn as a liability.

Is this correct, or is there a better way to think about this?

The opposite is more correct. So you probably remember it wrong.

The isolated central pawn adds to the attack, but can be a problem when there are fewer pieces on the board, as it is hard to protect (no pawns to protect it). Often you will have to sacrifice it and try to hold the draw a pawn down.

That is an oversimplification and not even true.
There is a whole book about it:
Isolani Strategy, Strengths and Weaknesses of the Isolated Queen's Pawn - Mikhalchishin
The isolated pawn is an endgame weakness, as it is easy to blockade with a knight or later the king. The static weakness is often compensated by dynamic factors like the open files next to it and the two outposts it provide.
