What can a university student do?

I think you better concentrate on your study and not for other things. Once you mixed up all activities with your study, facing unsettled problem, it will make worse to your educational performance. Better finish up your study at university and after your graduation you can start your indulge. If you fails in your study means your ruins yourself and your whole family.

If you want to take the responsibility of your family finance wise, then you better start a business and start earning. After establishing the business, you can take up the course in Long Distance Studies of the University and through internet, you can take lessons.
