I absolutely hate needles myself. Then I joined the Army, got no say in the matter and got jabbed in the arms more times than I care to count (I remember getting the smallpox vaccination during my first pre-deployment, 15 jabs one right after the other, plus we all ended up getting 2 or 3 other shots on top of that, needless to say, that was a nice sore day). Now whenever I need a shot or something I just sigh, turn my head and be glad it's only one stick!
Conversely, thanks to CLS, I've never had a problem sticking someone myself, never had a problem starting an IV in classroom (never had to do one in the field though)
