I guess that your environmental conditions genuinely matter when you are performing a job.
I never realized how sensitive I was to external stimulation until fairly recently; For most of my life I have been able to live & labor in a fairly controlled environment. I have lived alone & I have worked from home. As such, I have been in charge of my entire set of environmental conditions, from the lighting to the sounds that surround me. I was in for a giant  surprise when I went back to working in an office a few months ago. Suddenly, I realized how reliant I was on my indoor air handling devices & thermostat tyranny at home. I never genuinely noticed before but my indoor air temperature control equipment played a giant  part in my yearly work. Because I was typically at apartment with my own central heating & cooling system I was able to adjust the thermostat however I wanted to. This month, my a/c unit & forced air furnace were typically running throughout the afternoon. I got certainly accustomed to the sound of my a/c unit outside my office window. I was used to hearing the forced air furnace chugging away from the basement. When I entered the new workforce & returned to working in an office… Suddenly it was way too silent separate from an ancient Heating & Air Conditioning system running all the time. After several unproductive weeks wishing that I had my normal indoor air handling devices to drown out the sounds of my coworkers I went out & obtained a background noise machine.
