I work from home and my office is our MIL suite. Since I do not share personal office space I am more detailed and probably would not be able to have things the way I do if I were in a corporate office like I was years ago in marketing at a major snack food company.
It is SO easy to just come in and let things pile up in my office since it is right off the hallway from coming into our house from the garage. I get stressed out over that. My hubby has boxes of literature, formulations and patents from 20+ yrs in my office. I hate it but I can't get rid of them because we do fall back to some of that research and data from time to time when coming up with new products. SO...
I have everything labeled and in white banker boxes for easy access yet they are stacked nicely. He can get whatever he needs with little mess.
I keep one of those 6ft tables in my area for gift wrapping, setting up my packages for FedEx, and workspace when I need something bigger than my desk.
I keep a fan (with remote control) and a heater (with remote control) close by for my temperature control.
I listen to Pandora on my computer or hook my IPad up to my Bose mini speaker and listen to Pandora. I like to listen to Enya, piano, orchestra, Bruno Mars, Theivery Corporation and many more. I keep them going in the background. You can program Pandora to play whatever you are in the mood for and I like that!!
Since I am busy with a lot of paperwork daily. I keep my desk drawer set up with files I need on a daily basis, all customers and vendors are in abc order, all accounts payables are in a numbered folder so it is an extra step to keep track of AP.
I have 2 files set up in my desk area for top drawer and 2nd drawer of my filing cabinet. When my abc order files, top and 2nd drawer files are full, I file everything accordingly in the file cabinet.
I like neat space. I do have a small basket with some of my favorite treats and dog treats as well since my shadows stay with me in the office as well.
I also have some Bath and Body plug ins that smell nice. I love the ones that smell like the beach.
Best wishes to de-stress your office space!
