I might have to disagree with you when you say picking a career path/major shouldn't be about doing what you love. That runs counter to everything I've learned in life. I'm by no means a stellar example of financial success... but the challenge and reward of working for the local wildlife rescue (despite the minimum wage), or the satisfaction I feel doing work I both love and am well-equipped for, despite struggling through meager times to get here, have more than made up for it.
On a similar note, I may not be able to artfully combine my Anthropology and Biology dual majors into a well-paying or prestigious career, but I love to be able to integrate their lessons into my human experience. Having the language to understand and draw paralells between the evolution and working parts of organs and lifeforms, and the evolution and working parts of cultures and societies is something I'd not want to trade.
I know that the brand of high-mindedness that I let pilot my life is pretty unprofessional, and doesn't really translate to career success, but it's generally left me contented, and well-equipped for all the non-fiscal aspects of life. Total education, and finding love in your work, is vital to my model of life success.
EDIT: I should add that I liked the sound of most of your proposed seminar, and it sounds like it could really make a difference in the lives of young folks stepping into the uncharted waters of collegiate life. You do have a lot of great entrepeneurial ideas, and should totally carry more of them out.
