I've got to agree with bobonuts. Keep it simple...what you "want to do in life" is enjoy your life/be happy with your life. Not hedonism but just doing whatever is satisfying and don't worry if it is a struggle.
It could be worse, you could be 40 and not know what you want to do, or 40 and know what you would like to do but not know how to get there or if you have enough time to change direction. You're 24...if you head in a satisfying direction and put a little effort into it things are going to work out.
Concentrate more on recognizing when you're not heading in the right direction, and not allowing yourself to get too far down the wrong path.
Without getting into the details, I have been doing a job that pays extremely well and was exciting but is not sustainable in the long term. I always figured I'd just give it up when it didn't work any more, go to grad school, and transition to a regular career. With the shitty economy, leaving my job is now a huge risk and staying in it will lead to the destruction of my marriage and family (too much travel, 90% of my colleagues are divorced). My wife and I are now both preparing to go back to school (while I continue to work) and it will take 3 years to get to where I can leave what I am doing. I'm really too tired to think about going to school but I have to do it...
My point is do something you enjoy and if you have to give up something for it (location stability in my case) make sure that you either have a solid plan how to move on or that you are willing to give those things up for the rest of your life.
