At work, I've been told I come off as a "negative nancy". When asked for a review or my thoughts, I generally discuss the negative aspects or areas for improvement first. This isn't because I think that everything everyone has ever done sucks; it's just that I don't get the urge to waste time with compliments and positive banter. Time is better spent improving! Onward upward! However I don't want to come off as unpleasant and I'm looking to change. Anybody have books or advice on how to be a more positive person?
