Invulnerability is a foolish quest, because to strive for it is to also strive for lonliness. If ever you've adapted yourself to not be affected by pain, you've also sacrificed pleasure. And it's some of that pain that eventually GIVES us pleasure, in some form or another, it's just all in the way you look at things. And if were to be able to not recognize and understand pain, we would not be able to be there and help out our loved ones when they were going through some as well.

Courage isn't not being scared, it's just not letting the other guy know you're scared. As a little secret, I'm still scared about college to this day, and always have been.
