5 Horrible Habits You Need to Stop Right Now
Do Not Email First Thing in the Morning or Last Thing at Night “The former scrambles your priorities and all your plans for the day and the latter just gives you insomnia,” says Ferriss, who insists “email can wait until 10am” or after you check off at least one substantive to-do list item.

Do Not Agree to Meetings or Calls With No Clear Agenda or End Time “If the desired outcome is defined clearly… and there’s an agenda listing topics–questions to cover–no meeting or call should last more than 30 minutes,” claims Ferriss, so “request them in advance so you can ‘best prepare and make good use of our time together.'” Sam Edwards—Getty Images/Caiaimage
Do Not Check Email Constantly Batch it and check it only periodically at set times (Ferriss goes for twice a day). Your inbox is analogous to a cocaine pellet dispenser, says Ferriss. Don’t be an addict. Tools like strategic use of the auto responder and Boomerang can help. Jetta Productions—Getty Images
