What were the options that Sophie was dreaming of? Why does Jansie discourage her from having such dreams?

Sophie was dreaming to start her own boutique and probably be an actress too. She wanted to become famous and successful as Mary Quaint who was a famous English fashion designer. Jansie discouraged Sophie from having such dreams as Jansie was very realistic and knew that after school they were destined to work in the biscuit factory. She knew that to buy things they need money which they don’t have.
