According to current research, in the determination of a person's level of happiness, genetics accounts for about 50 percent; life circumstances, such as age, gender, ethnicity, marital status, income, health, occupation, and religious affiliation, account for about 10 to 20 percent; and the remainder is a product of how a person thinks and acts. In other words, people have an inborn disposition that's set within a certain range, but they can boost themselves to the top of their happiness range or push themselves down to the bottom of their happiness range by their actions.
