What is your advice Bobby?

Maybe one of the books in Judit's award winning Trilogy Judit Polgar Teaches Chess Trilogy by Judit Polgar (jpchess.com) Just found this, a bio on chesscom : Judit Polgar | Top Chess Players - Chess.com

Right now Hou Yifan | Top Chess Players - Chess.com at #87 Hou Yifan is the strongest in the world. But she has not known the advice of Bobby Fischer

"[I] Don't listen to weakies" - Fischer.
Jokes aside, Julia was essentially playing chess since the age of 5 and her parents were backing her. Fischer on the other hand was broke and I believe his mother didn't support his ambitions. Whatever advice Fischer could've given, it wouldn't have made a long-term impact. We'll probably never know unless one of the Polgars decides to disclose it (unless they already have).
Regardless, it's nice to see a picture of Fischer smiling around other people.
Anyone has any clue about what could have been Bobby Fischer's chess advice (s) for the Polgar sisters?
