Motives are another important thing to consider when studying the personality. Motives are forces that are influenced by something that someone needs. When a need is not met, an individual will have a motive to fulfill that need. For example, every human being has a need for water. The motive would be thirst. The need for water influenced the motive to no longer be thirsty. A press is an external event that acts as a trigger for motives. Using the same example as before, a thirsty person may want to drink water by seeing a cold cup of water, which serves as a press.
