I would ask them "what is something you want to build? something simple?" and help them. Mentor them. Teach them how to research on the internet the problems they are looking to solve (sometimes people just don't know the right words to look for). At least me as a teenager I was a very project driven person. It gave me a good feeling to build something neat. Much more interesting than classes and such. Or is this about a career (teenager could mean someone about to go to college soon)? Maybe introduce them to some people that do the job they want, if it's not you? I'd ask them what they want and how they work, and really figure out something that works well for them.
