We all have them: those days when nothing goes right. To avoid taking the stress home, try doing three things at the end of a bad day:
Clear your mind: Take a few deep breaths. Think about the things that matter to you outside of work. Prepare yourself mentally to walk out the door and leave the day behind.
Do something easy: Send off a report, reconcile a balance sheet, or reply to a few straightforward e-mails. Get some things off your to-do list to restore a sense of control.
Get up and leave: Once you've completed the task, don't check your email once more or stop by someone's desk. Just leave.
