Two minutes of “Eye of the Tiger” will rejuvenate you. If you get along well with your team, and the environment allows for it, play the song on your speakers so everyone can wake back up. Otherwise use headphones.

Any time you engage with other people (sales or otherwise), your nonverbal cues say at least as much as your words. Even on phone calls, while people can’t see your smile, they can hear it. Plus when you smile, it makes the people around you smile.

Engage socially so you look forward to coming to work. You don't have to be best friends, but you shouldn't be strangers either. If you work remotely, consider holding daily Skype calls for 10 or 15 minutes with a mentor or friend.

Go sit somewhere else. Weather permitting, you should go outside. A change of scenery can clear your mind. If you have a favorite spot that isn’t your desk, go there. If you work from a laptop with wifi, do some work from that new location and see how it inspires you.

Don’t spend all day thinking about the vacation you just went on or the getaway you’re leaving for on Friday. Be at work when you're there. This also means you should be at home when you're home. Try not to take your work with you at the end of the day.

Drink water. Drink lots of water. There’s science somewhere behind this suggestion, but the most important point is that staying hydrated makes you feel better.

If you sit for a long time, try standing in between emails or phone calls. Stretch your legs out to avoid problems down the road like restless leg syndrome.

If you stand or walk for a long time, try sitting for a minute. You don't want to be so physically worn out that you can't handle the mental stress of work.

Your smartphone can help you accomplish a lot...or absolutely nothing. Establish a "no phone zone" or set periods of time where you won't check notifications. There are a few apps to help you with that, but disciplining yourself at work will help you reconnect with the world outside of work.
