okay, make sure your hands arent super wet, drop a couple drops of the saline solution into the contact, and then put it on your eye just below the pupil, and then look down and push it gently with your finger on your lower eyelid onto the pupil. You'll know its gonna stay on when you feel the air bubble trapped between your eye and the contact push out.

it takes practice, but I've worn em for a couple years and I can do it without a mirror now.

Nice move btw, contacts are awesome. Get the ones you can wear overnight, otherwise it can be kind of a hassle if you pass out drunk somewhere, and wearing them too long can give you an eye infection, because when you sleep your eye wont get any oxygen through the contact.
