Do not answer calls from unrecognize
d phone numbers. […] It just results in unwanted interruption and poor negotiating position. Let it go to voicemail and relax.
Do not e-mail first thing in the morning or last thing at night. The former scrambles your priorities and plans for the day, and the latter just gives you insomnia. E-mail can wait until 10am, after you’ve completed at least one of your critical to-do items.
Do not agree to meetings or calls with no clear agenda or end time.
Do not let people ramble. Forget “how’s it going?” when someone calls you. Stick with “what’s up?” or “I’m in the middle of getting something out, but what’s going on?” A big part of GTD is GTP — Getting To the Point.
Do not check e-mail constantly — “batch” and check at set times only. I belabor this point enough. Get off the cocaine pellet dispenser and focus on execution of your top to-do’s instead of responding to manufactured emergencies.
Do not over-communicate with low-profit, high-maintenance customers. There is no sure path to success, but the surest path to failure is trying to please everyone. Do an 80/20 analysis of your customer base in two ways–which 20% are producing 80%+ of my profit, and which 20% are consuming 80%+ of my time? Then put the loudest and least productive on autopilot by citing a change in company policies.
Do not work more to fix overwhelm — prioritize. If you don’t prioritize, everything seems urgent and important. If you define the single most important task for each day, almost nothing seems urgent or important.
Do not carry a cellphone. Take at least one day off of digital leashes per week. Turn them off or, better still, leave them in the garage or in the car. I do this on at least Saturday, and I recommend you leave the phone at home if you go out for dinner.
Do not expect work to fill a void that non-work relationships and activities should. Work is not all of life. Your co-workers shouldn’t be your only friends. Schedule life and defend it just as you would an important business meeting.
