As a current student, I think what you are doing is quite wonderful, and having just read PG's 'What You'll Wish You'd Known' Speech, I think that such a talk like this could be incredibly powerful and might make a difference in some lives. What I would stress is the abundance of possibilities available, just the sheer amount of magical discoveries that they can go on to accomplish, or discover an hour after your talk (on that point, stressing action now, what they can do as a student is paramount to reaching them and getting them to really take you up on your offer). Too many times, speakers come in and give these lackluster maxim-filled speeches about life, and roads ahead of them. I would try to really imbue within your audience the fact that they can act now, and grasp at openings that could propel them to discoveries 10..15 years from now.

I do think it is quite admirable to try to plant the seeds of this career and of possibilities in these fifteen year olds, and think you could really make a difference somewhere.

If you need anyone to bounce ideas off from the perspective of a current student or give any critiques, feel free to shoot me an email (in my profile), and I would be happy to look it over. Good luck!
