I live at the bottom of a glass hill. You can’t go around it. You have to go over it. I will make you a pair of iron shoes that will do the job. In exchange, however, I will ask you to serve me for seven years.
I watched a young woman come to the hill. She was sobbing and seeking a way over. She tried to climb on the glass but failed over and over again. When she found her way to my house, I gave her my offer. Seven years of service for a pair of shoes that will get you over the hill.
She was impatient and tired, but she agreed. I told her it takes longer than you think to climb a glass mountain, but you’ll never surmount it if you’re not willing to come and work for me.
