Career Counceling

Years ago I took the Myers Briggs personality test, and found out I am an ESFJ. If anyone has any knowledge of this personality type they would certainly not dispute this. Now I need to choose a career.
I like careers that have a lot of contact and interaction with other people
I want to help nurture and care for people and communities
I want a clearly defined jobs
I need to know my job is useful, needed and wanted
I need personal feedback on my positive contributions
Now, I've said that I don't want to be a secretary, but damn, it sounds like I would make a good one. This would also match my personal thought that I do NOT want to work shift work. It would also help if I worked for an environmentally friendly company.
Any ideas of what I should do? I don't want responses like: "have kids", "travel", because don't worry, I plan on doing those things real soon too.
