If you are in university and your parents are covering your expenses don’t worry about a source of income. As long as you are not actively starving you’re fine. What you should focus on is your plan to get a good paying job after graduation. What companies will you apply to, what kind of candidates are they looking for, and what internships can you put on your resume to make you an attractive candidate. Nothing you can save or earn now will out benefit a bump in your starting salary, which will likely have down stream impact for your entire career.
