A story was introduced about a lady who was suffering from obesty. She was on a diet. But it was not effective. Because she continued her bad habit,too. As she likes confectioery, she kept it near her self. And she had it sometimes. It was very convenient for her.Docter found it and odered to throw away it. After that her diet was effective. I found from this story that to keep convenient condition is nice for our aim. I began to keep a paper and a pen and a dictionary near myself to lrean English. It was good way.
