We've all done some pretty dumb stuff. Let's share and learn from each other. Enter your sales or marketing mistake as a comment. Enter your name and include a link to your website, LinkedIn profile, blog, twitter name, Facebook, or whatever other site you use. Subscribe to comments and feel free to share. Hopefully, we won't have too many more than 101!
I'll go first!
