I have no idea how you can just get a PhD without knowing what you want it in. That's like saying you want to be in the entertainment business but you have no talent to do anything worth seeing.
^ this is how I feel also.
I did Electrical Engineering in undergrad and took a job that paid for a masters program in Software Engineering. The pay increase was rather substantial after I completed the masters program, but it was a position that required a masters degree. By that, I mean it was just a box on a form to put a check in. In some ways (and this may vary by industry and location), with so many more people going to college than before, a masters degree is becoming the new bachelor's. I
did learn a decent bit from some of the classes in the masters program that was applicable to my current job, but the work experience did a lot more to improve me as an employee.
I originally had no plan to get a masters so soon after school, but it was a great opportunity and I'm glad I did it. There's no way in hell I'm gonna get a PhD, though...basically because what everyone before me said is truth. I've got several friends who took a paid-for PhD opportunity (with the same employer), and every one of them hate it (for the same reasons I knew I would). A few have already dropped out, because they went into it thinking it's just another stepping stone, but the decided it wasn't worth it in the end. The ones who plan to finish still hate the stress, lack of free time (they're still working afterall), and just the overall headaches that come with it.
It's entirely up to you to put forth the effort for a PhD, so listen to those folks and get an idea of what field you want do research in and
why, and plan ahead for what you want to get out of it (a certain job or a particular field of interest, for example).
Is it for love of the field of study/research/teaching? Well it certainly doesn't sound that that describes you at the moment. But if you answer yes here, it's a no brainer I guess.
Is it for money? Do some research and find examples of specific jobs requesting a PhD and how many of those jobs are available. For certain desirable positions, the PhD might give you a competitive advantage. For others, you might not make any more money than the guy with a B.S. who's been at the company a few years. For jobs that are not requesting a PhD, keep in mind that companies might view you as 'overqualified'--meaning they don't want to pay you extra because you have a PhD, think you might scoff at 'lessor duties', or the like.
Is it for the respect? I fully believe individuals are due some respect for obtaining a PhD...it takes a lot of work and dedication. It's an accomplishment, and a badge of honor. Just don't act like a pompous ass like someone I know, or people will laugh at you behind your back for throwing your credentials around (I'm not suggesting you're like that, but I just had to add this comment). Example: said PhD guy had a heart attack (which is no laughing matter of course, but what follows is), and while he's in the hospital he insists on being called Dr. White--names changed to protect the innocent. Why does he do this? Because his brother is an M.D., family practice, who has had a working relationship with the hospital for nearly 20 years and is fairly well known in the area...so the other wants everyone to know that HE can be called doctor also. But of course, all it does is cause hordes of people to call the brother's family worried that
he is the one who had the heart attack. And no one in that setting cares that the sick patient has a PhD in physics. It's completely irrelevant. There's a time and place for everything.
Wow, sorry for such a long post...but you need to be used to reading droll text anywho
