Do you eat at your desk often? I know you do it. All the time. When 12 Noon rolls around, you think, "I can run down to the cafeteria, grab some lunch on a tray, and run it back up to my desk so I can catch up on email."

That's Stupid.

Candidly, you really need an extra 30-45 minutes to cover email? Email where 60-70% of it is unimportant? (read my previous post on email behaviors)

Here's an idea — go out to lunch. Meet someone outside of the company. Why?

It gets you out of the building. Anything that changes your location changes your perspective.
It gets you connecting with colleagues OUTSIDE of the company that you currently work for. You never know - you might meet someone that might offer you a better job. Or you might meet the perfect person to hire for that new project.
You meet new people. New ideas, new viewpoints, new humor, new stories.
You get to eat great food - the worst restaurant is usually better than the best cafeteria. Yum!
You get to see the sun. Vitamin D - here I come!
You breathe FRESH air. You get exercise outdoors. You might get a better parking spot when you return!

Bottom line — get out, connect with new people and you will see your career blossom. Stay indoors, cocoon in your cubicle, and you will see your career atrophy. Trust me.
