Love/Hate relationships

I'm loving life, but I have two things that consume a lot of my mind right now and I don't know what to do about it.

My job--
This is a tough one. I have days that I absolutely love the kids that I work with and I feel that I've made a difference for them.

On the other side, there are days that I can't stand it and can't wait to go home at night.

The sad thing is that there is really no middle ground here. Which, in a way, is good because you might as well like something all the way, as opposed to just half way, but there's too many bad days and I don't like that aspect of this whole deal.

So...I'm left with a choice. but given that jobs are quite hard to find right now and this job works with my school sched, (for now, it won't next semester!) I think I should hold onto it.

I just don't know what to do for later. this creates a problem.

2nd dilemma: My car--

I love it because all the 'stuff' works on it, it's newer than my last car, it runs well, etc., etc.

I hate the gas mileage it gets, so badly! I absolutely cannot stand to go to the gas station and think of how much money I am wasting!

So, I need to sell it. The problem comes in when I have to decide what to do next.
Should I drive my ratty other car that drove me nuts in the first place and prompted me to get a different car? Or should I get a nice car that I really want? There are pros and cons to both, of course...mostly, the payment situation on a new car.
I could afford a payment because I don't have any other major bills that I would have when I graduate and start 'real' life, if you will.
but...if I just get a decent car for cash, then I could save said money and buy a car that I really, really want when I graduate, get a real job and have more financial stability than I do now.
what about paying for grad school? adding a car payment on top of that doesn't sound very fun.
what about now though?

uhhh...I hate making these decisions. even though when I think about it, I've done it before and it's easy. A car or measly job now pails in comparison to deciding where to go to school, what to study, blah, blah, blah, all of which have already been made.

I'm usually a very decisive person...

until next time, when I've made some decisions.
Peace
