The best way of approaching student loans? You don't always have to borrow the full amount, borrow what you need and a little extra just in case of emergency expenses. If you are not working and/or no financial support, it's normal not to pay the interest while in school.
You could choose to pay your loans off immediately or spread it out under the standard 10 years unless your debt load is excessively high in proportion to your income. I would take the alternative approach (option 1), tell your family to save their money so that you can open an office quickly after you graduate (work part-time somewhere else while ramping up). That's probably the fastest way you can get out of debt. However, the other approach (option 2) is to use your family's money to pay off your loans or pay off your school tuition, work as an associate for awhile, then open an office or buy an office. The path to take depends on your priorities.
Option 1 is higher profit, higher risk, more pressure to succeed. In option 1, you have student loan debt and a practice that needs to start making money quickly.
Option 2 is lower profit, lower risk, less pressure to succeed since you have taken the debt burden out of the equation.
If you want a happy, reduced stress life, option 2 would provide that for you.
If you want to get out of debt and maximize profit/potential, option 1 would be a better choice, assuming your office does not fail.
