Save your time by asking people not to email you.
We all want to free up a year or two of our time to focus on other important things.
I learnt these techniques a couple of years ago. They allowed me to give more time to getting more work done, which developed my career.
Think about it: How many emails have you received today? how many have you actually managed to read? out of those you read, how many needed your action and how many gave you important or relevant information?
