If I could earn a living doing what I love most it would be working in a hospital as a social worker. The reason I would love this job is because I would be able to help people. That has always been my goal.
The way it would change the world is by helping some of those families deal with whatever their family member is going through. Many of the parents and grandparents and siblings could be helped by e little show of kindness and caring. If they feel better then they will, hopefully, move on and pay it forward.
