Your cubicle next to sales/lunch room where the people next to you are loud, noisy, and talk about nothing related to what your doing.
What do you do next if moving your cubicle to someplace quieter is not an option?
Change your work schedule so you have quiet time before the office opens.
If you have some flexibility about being at your desk, you can find a lot of secondary spaces which go unused. Wiring closets, conference rooms, file rooms, storage areas.
