Two simultaneous part time master's degrees while working full time I hold a BS in Mathematics with a minor in Statistics and I've been out of school for several years. I recently began applying to part time online master's programs in Statistics and Computer Science. I've been accepted to the online MSCS program through Johns Hopkins University and I'm hoping to be accepted to the online MAS (Master of Applied Statistics) through Pennsylvania State University as well. My goal is to earn both degrees, and with expertise in both disciplines become the ultimate statistical programmer!

The catch here is that I don't want to (and can't really afford to) leave my current job to pursue school full time, hence the part time online programs. I could do one degree after the other, but that would be another 8-10 years I'd be in school, all the while working.

It's useful to note that I'm already a statistical programmer. Degrees are helpful, especially if at some point I'd like to transition to being a full-fledged statistician or a more general-purpose programmer. In my mind at least, it offers a level of career flexibility not readily attainable with just a bachelor's or even a single master's.

But my question is this: Is working 40 hours/week and taking two online master's level courses at a time in two different subjects from two different institutions completely insane? My family sure thinks so. Does anyone have experience or input they could share?
Better to do one or the other. What you don't want to do is to fail out of either program. Pick the better/more prestigious one and do it. Also, I don't see how stacking up masters's degrees really helps you. I can see how one masters would help, but I don't see what value the second would add.
