Iron rule on the way to success...
Rule 5
- Check the mailbox at a set time.
Response to e-mail as they arrive to distract and dissipate the attention. Highly successful people know that they can't achieve a lot if you are distracted by everything that requires their attention. Instead of constantly checking your Inbox, check your emails a maximum of two or three times a day. Select the amount of time during which you have to reply to emails and sort the ones that require an immediate response and those that can wait.
