Any parent will tell you that inducing a desired teenager behavior while maintaining the illusion of free will is a simple wording trick:

"I would love to see you succeed in any career you choose; of course, society values things very materialistically, for example an art major will never afford a fancy car and clothes, a big house with a pool and trips around the world. But you will have your love of art and lots of art albums if that's what really maters to you."
