I'm new at contacts...Any tips?

Ok, I just got contacts today and started looking them up online. I have two weeks disposables and it scared the living **** out of me that just ONE small harmless germ or virus could make you go blind for good. What do YOU do when you use your contacts? How do you disinfect them? I read that the saline itself doesn't do anything...just something to rinse them off. So I'm wondering what everyone does themselves to prevent this, and how to clean them, etc. Help? ^^;
