Doesn't go for me, I love talking and meeting people. Well, then again I draw way little, despite wanting to work in the field.
But I got my first gig cause I hung out at this forum and thus got noticed by people, so I can only agree with the original thesis.
Also, "being a lone" wolf is a pretty bad excuse for never networking. Maybe there's an issue that goes deeper than just the self perception as 'lone-wolf', but if it's nothing more then just post an art piece, add someone you like from this forum to the MSNs and just be the littlest bit visible, it's sure to help.
