In the old yeshivas, every morning at dawn one of the rebbes would bang on each of the students' doors and call out, "Kumu, kumu l'avodas haBoray." "Get up! Get up to do the work of the Creator."
What a wonderful way to be awakened! There is a simple yet profound reason for getting out of a warm bed on a cold morning — to do God's work.
