To work or not to work???

I am going to be starting my entry level masters program in August and im wondering if i should continue on my job hunt to work at a hospital. I know when im done with school ( 2 years from now) it will be easier for me to get a job if i already have one foot in the door at a hospital. I'm unsure if ill be able to handle working as well as keeping up with this fast paced program. I want to get good grades and not be stresses out for two years but i also want to make sure that im not that new grad with no job leads months after i graduate. A little insight would be greatly appreciated.

I dunno what the job market will be like two years from now, but if it is still anything like today, you are going to want some related experience on your resume.
