Take care of your eyes.
Lets say that youre totally engrossed in a presentation that youve been working on for weeks. In fact, youre so absorbed in what youre doing that you dont realize that youre now sitting even closer to your screen. Just like the rest of your body, you need to give your eyeballs a break when you work from home. Protect your eyes by looking away from your screen every 20 minutes or so for at least 30 seconds or longer. That will give your eyes a chance to recuperate and avoid eye strain and potential headaches. Set reminders if needed.
