Future Direction?

Tonight is just one of those nights where I feel the need to write just so that I can see my thoughts in a tangible form.  I've been struggling here lately to  really be honest with myself about where I see myself in five years, and not knowing really frustrates me.  My biggest pet peeve (<---hate that cliche) is not knowing how things are going to turn out.  I still enjoy a good suspense film, and I love books that keep me guessing, but when it comes to real life; I always have this feeling that I need to know what is going to happen. 

Obviously, I am not capable of predicting the future.  If I was, I'd be a billionaire, and I would not be writing a blog. So, I run into the obvious problem of worrying way too much about the outcome of unpredictable events.  Also, I have a nearly impossible time making important life decisions.  For example:

I graduated college in December and I have a great job that I really enjoy. It has a lot of potential to just keep getting better if I keep working hard, and I am super blessed to be in the position that I am in currently.  On the flip side, I've always dreamed of going to graduate school to get a masters degree.  I want to be able to work and go to school at the same time, but I know myself, and I know that in order for me to do well at both I'd have to basically kill myself and give up anything I have that resembles a social life.  Essentially, the steps I would take to be an excellent student and a great representative for my boss would make me lousy at both.

So, the situation is as such...Do I commit to working in the insurance industry for the next 5, 10, 15 years and possibly do very well in a lucrative career? Or, do I apply for graduate school and see where it takes me?  Can I do both even though I don't have the confidence in myself?  Also, what's God's plan for me in all of this, and how will I know?

I'm not going to lie, I'm pretty confused about all of this right now, and it's really stressing me out...
