And to your previous post about "being a nice guy, needing deadlines set" sounds like something that I could write. The HARDEST thing to learn to say is NO. Best boss I ever had allowed my to YES my way into a huge hole. When I finally came to him and admitted that I was unable to meet all the demands (none critical), he taught me to say no. I STILL have trouble saying no, but I recognize when I'm getting in too deep and am forced to say no.
Good luck in your quest for the better job.
