I missed the tennis match between Venus and Serena this morning, but on hearing they were playing, a lecture I gave last year on temperaments, in which I used the Williams sisters as an example, came to mind.
One sister has a sanguine primary type, while the other has melancholic. In the lecture, I used this picture to illustrate the difference. If you know anything about temperaments, see if you can guess which one is which.
The Sanguine temperament is the air version, and is typically associated with a longer, lean body type. Think light and always moving.
The Melancholic temperament is the earth version, and is typically associated with a stocky and solid body type. It’s powerful but can be slow to get started.
Do you know your primary temperament? If not, this lecture MP3 from the conference (which comes with a PDF) has a guide.
Do you work with temperament? If so, how do you find it useful?
