My office...its in the basement. I work in a windowless room with two other ladies. I like my coworkers very much, but that basement...it gets to me sometimes.
So, how do I beat the blues.
Always take a lunch break and if possible go outside. Here's a little sun-dappled knitting project on a bench near work. Today it was in the 80s and really nice to feel sunshine. Even if its too cold to go outside I find a place to eat near windows. Windows!
Find a quiet place to recharge. Recognize this park? It was featured heavily in the movie '500 days of Summer'. It also happens to be about a block from my job. Sunshine, a light breeze, and a chance to appreciate the local architecture. Add a sandwich and I'm all set.
When all else fails...pretend you're in elementary school and its snack time.
