This may sound like common sense, but BE COOPERATIVE!  Lately, I have felt some stress in certain areas at work and it all boils down to people not being cooperative.  There is nothing to be gained from putting up road blocks and preventing people from doing their respective job.  Granted there are times when you have to stop people from doing things like giving out SA passwords to developers.  However, if they need your help, by all means BE COOPERATIVE.  It can go a long way in your happiness and theirs as well as your teams effectiveness.  That is all!  Enjoy!
