My line of consulting is not the most interesting, so I'll spare you all. But something I deal with almost daily is people not following simple instructions and not reading.
I know we live in an age of ridiculous warning labels, constant advertising, etc. so we tend to shut things out and not read them. But if you hire a consultant and they say 'please read this document',
please read it. There is little excuse for seeing "please sign but do not date this document' and then mailing a signed form we will not be able to use.
