The amount of schooling depends on what career you decide to pursue. Some careers only need an associates degree, some need an undergrad (4 years) and some require more. I currently work in business. My job only requires a 4 year degree, but more schooling never hurt anyone. If you are able to go to school then do it. If you are able to go and get that master's degree then I would jump on that train. Also something important to keep in mind, once you complete your 4 year degree and start in your career, some companies will help pay for you to go back and get your master's degree. Free money to better yourself! Take advantage if you can!
Hope this helps a little
