The Mount of Venus at the base of the thumb is very indicative of a person's passions. A high, well proportioned Mount means that the individual is full of energy, is outgoing, has a great deal of interest in life, and can be very vital and enthusiastic. Those who have a flat Mount of Venus, like a plateau, are very energetic. They like brainy pursuits, their friends are characters who resist the active mainstream of life, and their sense of discipline works best with specific mental activities, like the pursuits of writers, sculptors, lawyers, community organizers, and rock climbers. The shape of the thumb's tip is a strong indicator of the inner power. A pointed or conical thumb shows an impulsive nature and a person being perceptive, while a square thumb is a sign of common sense. A bulbous tip indicates a violent temper, and a tip that bends far back shows a far out personality, usually artistic or involved in an exotic mental pursuit. A person with a flat-tipped thumb is impatient and full of nervous energy.
