Teacher, counselor, social worker? In any job working with people, being thoughtful and considerate is a plus. You could also consider a medical job, like being a nurse or EMT. Being a librarian is a people-facing job where being thoughtful and considerate could really make a difference.
A number of people in this thread mentioned retail, and having that demeanor is helpful in the service industry. If you can make people feel welcome, and are friendly and helpful, you can definitely get ahead.
For a long time I’ve prided myself on being helpful and considerate. It helped me go from entry-level cashier type jobs to retail management over the last several years. But having a long-term career in retail is not for everyone. Staying calm, patient, friendly, and helpful in the face of every kind of unreasonable behavior, standing all the time and working nights, weekends, and holidays, totally wears you down after a while.
Long-term retail employees need a plan for recharging their batteries- delegating tasks at work, setting boundaries about your work hours, and spending your free time on activities that are relaxing and meaningful. And even then, it doesn’t hurt to think of the next thing. Can a retail job lead to a job with a vendor? In a warehouse or offie? etc.
