Going for a Masters in something you've never studies - have I lost my mind?

[SteveFoerster]

I tried to bang out my MA in four consecutive semesters, sixteen months, by taking three courses at a time while working full time (and like you, I have a family). And I almost made it. But in that last semester, I just hit a brick wall, to the point where I couldn't write one more sentence. I salvaged one of the courses I was taking, but eventually had to retake the others. Had it been any worse I'd probably have washed out of my program and lost most of the credit I'd accumulated.

I'm telling you this because something you said concerns me: "Obviously, some of my wasted time like Facebook and internet surfing out of boredom will need to go. I'm okay with that."

This isn't wasted time, it's down time. It may seem like what you're doing there is frivolous, but if you're anything like me (and I dare say like most people) then you need it. Abandon it at your peril.
