For others, you may be dreading going back. Just remember, you can choose your attitude. You can be unhappy and resentful. Or you can be glad that you have the opportunity for an education. You can be happy that in these times of unemployment, you have a job.
Getting that education, getting that paycheck...it's worth it. Keep at it. You'll be glad you did. Just decide that it's what you want. As I've quoted before (from "Soak Up The Sun" by Sheryl Crow), "it's not having what you want, it's wanting what you've got."
