I am happy, but I feel like something BIG is missing in my life.

My life is absolutely great! I am happy with everything. I love my family and friends to death! I love myself. I am proud of myself for completing university. And now I am looking for a career. Is that what's missing? Finding a job I enjoy doing? I don't know. But I feel like something BIG is missing in my life. I don't know what it is, nor am I going to ponder upon it. But I hope that someday I won't feel that "gap" in my life.
