Would you let a teenager choose your career?

Would you let a teenager choose your career? If you went to college, that's basically what you did. And what I did, too. At 17, I wanted to be a marine biologist. then at 19, I changed my mind & became a graphic designer. I'm so happy being a designer, I can't even imagine how different my life would be, if I stayed with biology major.

Now, I'm a mom. And I see it from a different angle. My first son was a mechanical engineer major. But the rigors of college, combined with late night video gaming with friends, led to a dead end. Switching majors to forensic chemistry, at an easier school, has been a good move for him. he's working in a chem lab over summer, and enjoys the work, which indicates for me that this is the right direction.

Middle son is a senior. He's smart, tests well, works hard, etc. But he's changed his mind about majors a few times: neurology, bioengineering, mathematics, with a computer science minor, or a music minor. I really want him to go into college undecided, and find out what he loves to do, and pursue it.
