I'm the oldest of three - three years older than my sister and seven years older than my brother, who is mildly autistic. Even though I'm a ESFP, it's always been at odds with a strong sense of responsibility, compassion, a good work ethic, and the need to serve others. I'm very hard on myself and sometimes don't feel that what I've done is "enough" for others or for myself, or to make other people happy. I think this is a combination of my personality and the stereotype of the responsible, overachieving older child. For a while I thought I was a 3, but that doesn't quite feel right.
