Mark Boulton, on asking people to formally write down their requests:
Next time someone asks you to do something, try it. I bet 3 times out of 10, they say 'oh it doesn't matter'. You'll have that time back. They'll be a little wiser and have a lower heart rate.
Good post. Jump over to his blog and read it. I may take something from this and instill it in my new job.
