He was once advising to learn computer skills, so he thought it was difficult. When he saw others learning English, he shook his head, says it was too hard to remember new words. He enjoyed watching TV, playing cards, smoke and so on. He felt it was hard for him to give away all these habits. Not long ago, he went to look for a job. When he knew talents were great needed, he sighed and regretted the time that what he had wasted. He told me how he wished he has worked hard in college and asked me not to copy his example.
