A method and system for motivating an individual to achieve a goal such as a weight loss goal, is disclosed. An individual sets a weight loss goal. A collector collects a deposit from the individual and takes a first or baseline measurement. The individual attempts to meet the weight loss goal via any means such as dieting, exercise, etc. After a predetermined time, the collector takes a second measurement; preferably the individual's weight. If the individual has met the weight loss goal, at least a portion of the deposit is returned to the individual. If the individual has not met his or her weight loss goal, at least a portion of the deposit is not returned to the individual but is kept by the collector. Additional measurements may be taken at more predetermined times. In addition, individuals may use this system for achieving other goals.
