Where does time go?

Spring break is over and I'm back at school, ready (or not so ready) to start again tomorrow. I was home for all of the break, and I got some good things done, but I also wasted a lot of time. Sure, my teeth hurt and I did need rest, but I kind of overdid the sitting on the couch thing.
As I come back to school, I'm coming back to a crazy schedule and a lot of things going on. My question is, how am I going to spend my free time? I have been praying for at least the last year that God would cause me to really hunger and thirst for Him, and I do more than I did, but my times in His precious Word have been way too shallow lately. I want to dive deep into His waters and have my thirst satiated. I want devotion to Him. I want to not be able to get enough. I realize that I contradicted myself there, but I guess what I mean is that I want to be so satisfied with God's word when I'm reading it, and then when I'm not reading it I NEED it.
May God teach me what it is to truly follow Him.
