Creative Environments

Your environment has a big impact upon your creative ability. If you work in a cubicle with perfectly white walls, boring furniture and elevator music, your creativity is probably going to be stifled.

Each person has his or her own particular environment that fosters performance. Some people do better in cold rooms, some in hot rooms. Some people like music, and others require silence. Some additional factors that affect performance are windows, lighting, color, decorations, food and drink, size of space, etc.

If you work in a group, try to be sensitive to the needs of your teammates. If you know that someone works best in silence, try to keep your music down (or use headphones). If some people work well on a sugar high, bring cookies and soda into your brainstorms [ For more on 'brainstorms' go here: http://www.braingle.com/mind/84.html ]. Simple changes around the office or classroom can have big effects on how people function in those spaces.
