Sadvice is a specific kind of badvice designed to discourage the recipient by fostering a hopelessness in him. The point of sadvice is to deflate aspirations by utilising a feeling of exasperated melancholy as a weapon.
Example: a writer will 'thoughtfully' tell another writer that a particular market is too difficult to break into and that it's not worth even trying and that he would save himself a lot of heartache by giving up writing altogether and doing something more in tune with his natural talents, such as working in a newsagent's.
