• Do not answer calls from unrecognized phone numbers
• Do not e-mail first thing in the morning or last thing at night
• Do not agree to meetings with no clear agenda 
• Do not let people ramble
• Do not check e-mail constantly , only...

If you define the single most important task for each day, almost nothing else seems urgent or important. The answer to overwhelm is not spinning more plates — or doing more — it’s defining the few things that can really fundamentally change your life.

Do not expect work to fill a void that non-work relationships and activities should. 

Your co-workers shouldn’t be your only friends. Schedule life and defend it just as you would an important business meeting.

If the desired outcome is defined clearly with a stated objective and agenda listing topics/questions to cover, no meeting or call should last more than 30 minutes.

Request them in advance so you can best prepare and make good use of the time together.
