The Mood Meter is our tool to help us build better self-awareness, even language for our emotion. On the x-axis, it says the word "Pleasantness." Think about it. Every morning we wake up and we think to ourselves, "This is going to be a great day" or "I wish I could pull the covers over my head." That's pleasantness. We want to approach, we want to avoid. We feel pleasant, we feel unpleasant. On the y-axis, it says the word "Energy." Energy has to do with both your physical and your mental energy. Think about it. You wake up in the morning, you feel energized, or you just feel depleted of your resources, and tired and exhausted. What we do to create the Mood Meter is we cross pleasantness and energy. That creates the four quadrants; yellow, red, blue, and green. Each of the quadrants represents different emotions. Let's take yellow: high energy, pleasantness, happy, excited, optimistic, joyful, elated, even ecstatic. Let's go to the green. It's still pleasant, but it's lower in energy: calm, content, tranquil, peaceful, relaxed, at ease. The blue and the red quadrants are unpleasant feelings. Remember, unpleasant doesn't mean negative; unpleasant doesn't mean bad. It just means they don't feel pleasant on the inside. The red quadrant is our quadrant that represents words like anger, anxiety, among their different intensities. You can go from peeved, to angry, to enraged, or from uneasy, to worried, to anxious, to overwhelmed. Finally, the blue quadrant represents emotions like sadness, loneliness, despair, even deep depression. Those are the four quadrants of the Mood Meter, and what they're helpful for is just taking everything that's going inside your head and putting it out into these four quadrants. It allows to take our complex inner lives, our feelings, and just say from the beginning, "Am I in the yellow, red, blue, or green?" You might even ask yourself, "Why am I feeling that way?" Then in turn, try to find the best possible word to describe your feeling.
