Your environment matters. While most people understand that their environment has an effect on their output and will notice certain overtly distracting sights, sounds, or smells, they do not realize the import of things they may not even explicitly notice.
For instance, research has shown significant output increases in rooms with a temperature of about 70 degrees compared to rooms that are hotter or cooler, and the differences seem to increase with how much creative problem-solving the task requires.
Designers will tell you that the colors in your environment matter; natural tones boost focus and efficiency, and warm colors boost creativity. Order in your environment reduces emotional friction and distraction from the task at hand. Measured beauty in a space increases courage by boosting the emotional reserves to tackle the task at hand.
Pay attention to your environment. Spend time researching what changes you can make so that your environment boosts rather than detracts from your productivity.
