When I started my job as a fresh-out-of-college SW Engineer, one of the more senior guys there suggested I read The Psychology of Computer Programming (I later went on to find out that this co-worker had some editor credits in it), which talks about ego-less programming. I did adopt a lot of the message in my work style, though I feel it goes a little far by suggesting an engineer not say statements like "I believe that..." or "I think this is better". I think that there's some amount of ownership, excitement, and conviction in an engineer's approach that adds to the project's success. There's definitely the chance that this goes over the line, and then I see examples such as in the article above ("oh, I've been here before so I know why this approach is the best so I don't need to value your opinion). Good read.
