Am I wasting my time?

I know this is question I come to almost every year without fail, but I can't escape the reality of it, am I wasting my life right now pursuing a degree I will never use?  To be a cop I do not need a degree, and really a degree won't go THAT far, to be a pastor I do not need a degree at all, and to be a carpenter (which I have a friend who works at one looking out for a job once one opens up) all I need is a high school diploma!

Am I wasting my time?

Could I rather be working day-side at UPS, going through Pastor school through Sojourn, maybe taking some classes at Seminary here and there just for equipping, not for a diploma?  Devoting much of my free time to serving, staying in shape, and enjoying God's good creation?  Getting out of debt by picking up a second job would also be nice!

I just feel like my life is characterized by being wasted, I spend most of my time doing something I can't see as functional in any way, and that doesn't sit well with me.  I can't sleep well anymore because everything I do THAT IS WORTH my time is really early in the morning and I have to jack up my sleeping schedule to do these things.  Such as serving the homeless, or attending leadership meetings, etc. 

I am depressed by the idea that I could be wasting months (8-12) trying to just push through to get the degree rather then investing in what I have a joy and passion in (and none of that includes the degree), and also the best way I can serve my church and God does not need a degree either (all those jobs, serving, getting out of debt, maintaining my personal health).

And how do I justify the time wasted for a degree I don't need when the job market gets worse and their is NO jobs at all, and those five years will haunt me for the rest of my life when I could've done so much more!

So am I wasting my time?
