<human>: Provide a brief overview of the text.

I'm in my third year of college and working towards a degree in Environmental Planning with a geography emphasis. By the time I graduate I will have a years worth of experience with Geographic Information Systems (GIS) which I thought would put me at an advantage. People have told me that I should get an internship before I graduate. However, I work 20 hours a week in order to pay my way through school. With a full course load, even in summer, I would not be able to take on an internship. Am I going to be at a huge disadvantage when I graduate with no internship under my belt? I was going to get one after I graduate but have been told otherwise.
<bot>: Should I attempt to take on an internship despite it not being monetarily feasible? Or will I be okay in the field by taking an internship after graduation?
