I do this ALL the time. I always thought it was just because I'm stubborn type and simply MUST complete something if I start it.

So I got my MBA. (Took me a while, but I did it.)

I did start a business at one time (several actually at different points in time). Had made flyers, brochures and a website and everything.

But personally? I don't think it's something to be fixed. I don't see it as a bad thing really. I think it's just a drive. Getting your MBA isn't necessarily a bad decision. (But I guess it depends on what type of day I'm having when you ask me about whether or not I regret getting mine.)

Even typing that out I thought to myself (no really, what the hell WERE you thinking??).

But I do have very black and white thinking sometimes. And I see my stubbornness of "I've started this, I'm going to finish it" as a good thing. Sometimes.
