h: pleasure, life, health 
h: anguish, death, pain
Etymology: The origin of this symbol and spectrum
Having “g”s to indicate smiles and frowns did not always convey the depth of an emotion—for faces do not usually give an indication of the intensity of an emotion. So I tapped “h”, the next door neighbor in so many words (light, delight, bright, to blight, straight, ghastly, ghostly). “H” gradually became another directional sign—the squiggle on top showing an intensely positive emotion such as joy or delight or laughter and the squiggle on the bottom to show an intensively negative emotion such as despair or anguish or slaughter.
Orthography: How to remember these symbols
Draw a straight line. Put an z-like squiggle at the top for joy and or one on the bottom for sorrow.
This can also be a bit more rounded, it depends on the edges of your joy or your pain.
Philosophy: How I use these symbols to embrace life
If I want to appreciate and live through the joy, I doodle the figure, thinking, here I am dancing on top of the world.
If I am down and in despair, I draw the squiggle and then the line, thinking, there is a way up. There is a way out of this.
I often combine the two—a line with z-like squiggles on the top and bottom shows the joys and sorrows, the pleasures and pains, that we all go through in life. When I am down, it helps me to remember to draw joy out of the sorrow. In my friend Aylah's name, I combined them, because she has experienced the highs and the lows and life from the top--and the bottom.
