I need to understand Career options for Being a Broker

I have watched Videos about sarbanes oxley act and Broker dealers with Financial Regulation Courses but Its all Regulatory insights which is way above my head. I am asbsoloute Begining level I havent even made my First Job Application yet and I am still wondering about the SIE.  I found a short on interview guides with wall street oasis so I recently joined. I was wondering if anyone can give me advice on the best way to go about this. To be Clear I have a Solid sales Background but no University Degree so I am starting from Scratch. Any and all help Advice or guidance would be Great.
