It's weird that you're asking this question because I too battle this question every morning when I get up. But I don't think it's so much "why do I love each day" but more like "Why am I here?". I've had trouble with that question for the longest time, trying to find my call in life. I found it, and I'm the happiest I've ever been.

I live for those who love me for who I am. My parents, my family, my few friends outside of family, my dog, my faith. Most important, I live for GOD and his son. Without Him, I'd truly be lost. I live for a new lesson everyday. Every morning, I get up at 6:30 to go to work. I babysit two kids 40 hours a week. It's defintely stressful (at that age with an attitude), but I get so much out of it. I see things from a different aspect every day, and I learn something from them everyday. It could be simple things, but in the end, it's a lesson that I haven't yet learned.

So I live to learn more about my faith. I may not understand everything that happens to me, but I trust my Lord enough to be faithful in Him.
