what is the right thing to do??

With careful time management you can do both. Work during the day and study in the evenings and at weekends. With study and qualification you can get a better job or business.

When you are still young and have all the time in the world, I think is better to first focus on your study, After that you can get a job. When you are settled with your job and you really want to then you can start your own business. The reason is simple starting your own business is not easy you need knowledge, and money...I speak from my own experience.. ALL the best..xx

The right thing to do is of course, to focus on where your commitment is. Since I am now having my own business, I am focusing in it, otherwise I will not be earning sufficiently and my business might crash.
