If you are interested in having a mellow day today, you are going to have to make it that way by saying no to more responsibilities. If it were up to everyone else, you would be busy as a bee. So it's all about boundaries -- you've got to set them, and you've got to be vocal about where they are. Make it easier on yourself by using face-to-face communication whenever you can. People get the message a whole lot faster when they are looking you in the eye.
