With few exceptions, the reason for obtaining a graduate degree is highly career focused. The big four: business, law, STEM (including health care) and education all either encourage or require some form of graduate education to advance and succeed in those fields of study.
Considering there is the possibility of a better career and/or salary awaiting you at the end of the grad school tunnel, it’s advantageous to take the proper steps while in your program to ensure you afford yourself the best opportunities as soon as you graduate.
