i read one quote from jace but i don't remember lire it, the book in which it is ou what was happening at the moment...could toi help me? it was "When life gives toi lemons, make lemonade..."

This is the only quote Jace never said. It has been confirmed par Cassandra Clare that she never wrote that and she doesn't know where it came from. People just posté it on Goodreads and it spread from there, I guess.

"When life gives toi lemons, make lemonade, and then throw it in the
face of the person who gave toi the lemons until they give toi the
oranges toi originally asked for."

Well I don't know who originally a dit it but that quote was in a TV montrer some years il y a called "Newsradio". It had Dave Foley, Phil Hartman, Stephen Root, Andy Dick, Joe Rogan, and Vicki Lewis. Anyway. It was Phil Hartman's character "Bill McNeal" who a dit it. That was back in 1997.

From "NewsRadio: Airport (#3.17)" (1997)
Dave: Bill, haven't toi ever heard the expression, "When life gives toi lemons, make lemonade?"
Bill: It's already happening. You've reverted back to what toi were.
Dave: This is what I am. A kind, friendly, reasonable person.
Bill: You've gotten soft. You're like one of those police chiens who's released into the wild and gets eaten par a deer ou something.
Dave: What?
Bill: Dave, haven't toi ever heard the expression, "When life gives toi lemons, make lemonade, and then throw it in the face of the person who gave toi the lemons until they give toi the oranges toi originally asked for?"
