What Should I Weigh

Right out of high school I attended 2 local community colleges…..a semester at each one. I was only going because all my friends were going and I took a whole bunch of nonsense classes. Like nonsense as in, one period was a religeon class, and then the next was human sex, and then child developement. I had no plans…..so I dropped out after a year. Well, about 4 years later, here I am, married with a 7 month old baby and a job working for Blue Shield of Ca where I have been trying to promote and move up but am unable to! I’m thinking about going back to school because it seems like everyone with authority here….or anyone about me in general….they all have a college background. So I’m thinking about taking some online courses so I can get something going and move forward in my career! I work in the health insurance industry and have been for going on 3 years now. I like it and there are so many jobs here that seem interesting to me…..so I’m thinking about staying in the business….or some kind of insurance. I have no idea what classes to take or what kinds of classes will help me in this field to get ahead. Any suggestions……I want to do it online cause it is literally impossible to go to class with my work schedule and taking care of my family. I was thinking maybe some business classes??? Should I try for a degree in business….I’m thinking that should take you a lot of places in case it turns out I don’t like health insurance anymore? Please help!! I don’t want to go to school again and waste my time!
