You didn't navigate, your gps did. I'm very glad you made it safely but
get real. If you don't know something, don't be proud of it. I can do
anything you can with a gps but can you do what I can? If not, why
not? You life is not the only one you are responsible for when you are
out there. If you need something, ever, and don't have it to use, and
it was easy to get, how stupid are you.

These things fall into the same thought train as thoughts I give my
pilot students - you can never use runway behind you, gas in the truck,
altitude above you, and in this case, knowledge in someone else's head.
