Be nimble and open minded, learn new languages, watch and discover new technologies, mentor people (don't be a land baron), and most important of all, DBAD (Don't Be A Dick). The guy you mentor may become your boss, and so might the guy you are a dick to. In the tech sense, DBAD typically means be nice, and don't be a technology nazi. There is no "perfect" technology for a solution. If the team wants PHP, and PHP works as a solution, DBAD, make it work for the team and don't force Ruby or Java down their throats.
