Symbols must be...

- clear and unambiguous.

- quick and simple to draw. You can categorize symbols by the number of strokes of the pen required to draw them. More than three is probably too slow.

- prepared in advance, and instantly familiar to you. Don't improvise mid speech.

- conslstent, if E is energy today, make sure it stays energy always and find yourself another symbol for environment and economy. Otherwise you will mix them up and make some terrible mistakes.

-organic. See below for an explanation of organic symbols.

...and they must..

- mean something to you. Copying symbols from other people can be a good idea, but symbols work because they create associations in the mind, in your mind, and the human memory prefers you to understand those associations yourself. So don't blindly copy symbols you see here or elsewhere if they don't create the right associations for you, if they don't "click" for you.
