2) Learn the difference between "in holster" and "out of holster" alerts. The majority of BB's will recognize when they are in the holster. I set mine to silent when out of holster. In this way, in a meeting, I can slip it part way out, and won't be interrupted. At our company, it is a major violation of etiquette to get buzzed or beeped in a meeting.
3) Use the out of holster at home. Then you can check it when you feel like it, and not feel tethered to it and feel the urge to go read it every time it beeps.
4) Learn to set a different alert for high priority messages. On the BB, these are called "level 1 messages". When on vacation, you can set your BB to ONLY receive level 1 messages. Tell your important contacts to use high priority to reach you.
5) Learn the filters. When I go on vacation, I set the filters to only get email from a few close friends and anything high priority. Vacation is vacation, and I know I have ruined my mood more than once getting an aggravating email that really could have waited.
