One side of their nature may, in fact, be described as perpetually pulling against the other, and although nearly always possessed with unusual intelligence, they often spoil their lives by lack of continuity in their plans and in their purpose.
They seldom seem to have a fixed idea of what they really want.

They change their plans or their occupations at a moment's notice, and unless they chance to be very happily married, they are just as uncertain in marriage.
They are the most difficult of all classes to understand.

In temperament they are hot and cold in the same moment, they may love passionately with one side of their nature and just as quickly dislike with the other.
They are very critical, and especially notice small faults or mannerisms in others, and they can express their views with a sarcasm that is as cutting as it is clever.
In all business dealings or affairs where a subtle, keen mentality is useful, they can out-distance all rivals, provided they are sufficiently interested to enter into the competition.
They are excellent in diplomacy and are gifted talkers, but they usually leave their listeners at the end of their conversation no wiser than they were at the beginning.
If taken as they are and with their moods, they are the most delightful people imaginable, but one must never expect them to be the same to-day that they were yesterday.
They believe that they are the most truthful persons in the world, and so they may be at the moment they are telling the story, but to them moments seem entire lives, and so in a day or a week the same story may have a totally different colouring.
None of these people will probably admit this to be true of his character, but a little study will convince anyone that it is a fairly accurate description of this subject's chief characteristics.
Mental work, especially the class of mental work that requires quickness of wit and change, appeals to them more than any other.

They make clever actors, barristers, and a certain class of public speakers, also diplomatists, stock brokers, company promoters, or inventors of new methods in business.

In all careers that require keenness of brain, they can attain success, provided they have developed a sufficient amount of will power and continuity of purpose to stick long enough to any one thing.
HEALTH Everything that can affect the nerves and the nervous system especially, afflicts these people.
Indigestion caused by nervous worry or anxiety, catalepsy, paralysis, afflictions of the tongue, stammering, insomnia, vivid dreams; to all such things they are specially liable.
