control of the situation or environment
People who value control, like to be masters of the situation. No matter what happens, they are ready to make decisions. They are also ready to take responsibility for their actions. Interest in control can arise from a person's need for security or ambition.
The ability to wisely control important matters makes people with such a disposition consciously lead their lives.
Remember that we can't control everything. Trying to influence people in our environment can have a negative impact on relationships.
