We went from an environment set up for our work to having to figure out how to set up our home environment to work. This means having to see our it with different eyes and expectations. Focus on what is your preference. This is in terms of lighting, desk placement and position. Look at natural light and fresh air to aid concentration and mood. Textures, plants, and objects can aid in creating an environment you want to be in. Take note of how posture: your desk and seating affect your work and mind. It takes experimentation, but these simple things can radically alter your mental health.
