Your workday is affected by 3 main factors: the setting of your work, the stress generated by your work, and the clarity or simplicity of your work. A pleasant outdoor setting makes you happier and less stressed than a stressful commute or a cluttered home office. Stress from constant cortisol release and heart rate increase, and overload from too many tasks can also decrease happiness in your job, regardless of the content. Simple tasks and clear obligations make for a clearer and more enjoyable work experience.
