The process of applying to jobs pertaining to my degree was the hardest thing I've ever had to deal with in my life. Harder than actually earning the degree, and harder than the job is itself. It was month after month of borderline depression, money worries, and hopelessness
So in my opinion, if you have the guaranteed opportunity to earn some money just take it. Worry about happiness later. I don't know how the economy is in Canada but I'm an engineering/physics graduate who actually got to the point where I was applying to movie theaters because I was running out of money. Fuck that shit.
