American has long been considered the land of opportunity by those from other countries. Americans, too, believe that the United States provides almost limifiess opportunity for those who want to open businesses on their own.

When he finally opened with a capital of $1,500, he set up his office in the kitchen of his home and his printing press in the garage. Due to his devotion to business his managerial skill, and his talent, Mother Earth now has a circulation of 300,000:
