What do you do when you are a woman with two young children? You spend a lot oftime and energy looking after them. What do you do when you are also divorced and have no money? You earn enough money to feed and clothe the children. What happens if you are also only twenty-four years old, and have hopes and dreams for a better life in the future? You look after the children, go out to work, and go to college, all at the same time. That is Nancy Wesley's way of life.Nancy gets up at 6:00 every morning, dresses her four-year-old Matthew, and two-year-old Anna, and cooks their breakfast. At 8:00 she takes them to the baby-sitter, who has two children of her own. Then she goes to school, and takes classes from 8:30 until 2:30. At 3:00 she picks up the children, and spends time with them at home. Two hourslater, at 5:00, it's time to go to the Wall-mart store where she works in the sports department, selling hunting equipment such as guns and fishing rods. She's home around 10:00, and then she tries to study. On weekends1 Nancy's ex-husband takes the children, and she works all day on Saturday and Sunday in the store. She's always tired.There is one thing that keeps Nancy going. She's determined to get her graduate degree, however difficult it is."The best thing in my life is the goal of my future, and working for that," she says. Theother important thing is the children."They are super, super intelligent," Nancy says proudly. "It's been tough for them. I feel bad about it. I know I get impatient with them sometimes. Sure, I have regrets about it. I don't want them to do what I did. I want them to graduate and get a good home before they have kids."Nancy is going to graduate next year, and then, she hopes, she'll get a better job, and have more time for the children. Maybe she'll have time to do some of the things that she did before, like playing tennis, or ice skating. She used to love sports, but she just doesn't have the energy any more.And who knows? Some day she might even get married again. Her first marriage lasted only two years, and when it ended she was left to pick up the pieces. Next time she'll know better."Women have got to know how to look after themselves," she says. "We've got to learn to be more independent."Nancy has learned the hard way.
