A Time Commitment to Become Certified To Teach

I am sad to report that one of my fellow bloggers on this site has taken a leave of absence. I understand she plans to return next year to continue. I sure hope so. The teacher certification program is a tough commitment. It is all time consuming but I figured if I can't honor my commitment to this program, how can I honor my commitment to my profession. It's not easy - there are some nights I can't sleep; there are some evenings I wonder if I have what it takes; and there are some weeks I wonder how I am doing this. I do this because I truly want to. I do have other commitments and I will just have to juggle like everyone else. How do you handle such a commitment or balance it with other commitments?
