A personality develops overtime, and during adulthood, these changes are strongly influenced by the overall self-satisfaction with one’s entire life and accomplishments so consequently, the happier you are is the happier you become and the question for those who don’t report self-satisfaction would be whether an “attitude adjustment” would result in continuous positive development. Most people would agree that your personality comes from genetics and doesn’t change, just your environment changes as you take on adult responsibilities. There are various stages that one’s personality passes through over the course of a lifetime. It is difficult to just say that most change occurs in one stage of life or another because even though most of one’s personality is genetic, there are still many every day influences involved. For instance, a person with a substance abuse problem may have a rapidly changing personality because of the fact that they have this outside influence. Also, one’s self- satisfaction plays a big role in the developing personality. According to research, one’s self-satisfaction tends to increase with age, of course, factoring in the gender and social class statuses variances.
