With the rising costs of higher education, I think it's difficult not to take your financial situation into account to some extent. Given your potential career path, you are looking at many years of education.
Ultimately, however, I would encourage you to consider what you would like to do and work backwards. If you have an interest in the medical field, what do you need to do to get there? How can you best utilize your time and resources to achieve your goals?
Although it's highly unlikely that you will be able to graduate debt free, there are decisions that you can make to minimize the amount of debt accrued. For example, selecting an undergraduate institution that is within your means may allow you to select a graduate school of your dreams. Not electing to take the maximum amount of loans offered or opting to live with roommates rather than a single room are other ways to reduce costs and minimize future debt.
With that said, ideally debt wouldn't be a significant factor in choosing your career. Selecting a career, in my opinion, should be based on your aptitudes and abilities, your willingness and motivation, and your life's goals and desires.
Good luck in your educational endeavors!
Another unfortunate consequence of debt is limiting the student's choices after graduation. If a student has a passion for pediatrics, but crippling debt, they may be forced to apply to residencies with higher future earning potential.
A typical experience would be to complete residency and become an employee of a group. You aren't able to pay down your debt much because you are saving to become a partner. You buy into the group and then start making partnership money. That's when you are able to really tackle that debt.
But typically you are looking at 10-15 years to pay back your student debt.
On a side note, watch this video which compares a UPS driver to a physician. It makes a lot of assumptions about debt and saving/investment, but concludes that the average primary care physician doesn't become financially better off than a driver until age 53.
Students who graduate with debt may put off life milestones such as buying a car, owning a home, getting married, or entering certain low-paying professions like teaching or social work. This is will pass. Follow your dreams!
always remember "High Risk = High Reward".
But before doing anything be true to yourself first & understand if you really passionate about doing that :)
