　　Lindsay Binegar of Greenfield, Ohio,made her first $100 at the age of four, when she won a prize for showing a pig from her family's farm to the local 4-H Club. Most kids would be thrilled to spend that money on toys,but not Lindsay."I didn't get the money; it went to the bank," she told The Columbus Dispatch.

　　Over the years, Lindsay kept on raising and showing pigs, and kept on winning prizes. Some were $ 100 for small wins, but she won thousands of dollars for championship prizes at county fairs. Before long, she earned an impressive amount of cash - but, aside from a purse when she was 14, Lindsay had never spent a dollar of her savings. By the time she was 18, she had got more than $ 40,000, which she planned to put towards her college education at nearby Ohio University.

　　But her parents said that if she continued living at home while attending school, they wouldn't have to pay for her dorm housing, and would be willing to cover the entire cost of her education. It sounded like a good deal to Lindsay. But what should she do with her savings?

Her father had an idea:buy a house, just as he'd done when he was young. He used the house's sale to help him buy the family farm where Lindsay had grown up and raised all those lucrative(赚大钱的)pigs. Lindsay was able to buy a house in Greenfield, paying for the entire purchase in cash. She did a bit of painting and then rented it out for $ 450 a month.
