Collecting recycled things in a neighborhood could be a good business for a kid to practice. It is not hard for them. you may escort your kid for the first three days to shy away from his feelings. Ask your kid first if he likes this business or not. Never force your kid. He may do it every weekend or during holidays and summer vacation because he must attend his classes from Monday to Friday. The kid must be aged 15 to 17. Eighteen years old may feel ashamed doing this business being a college student already, but if he is a wise guy, he may earn something for himself and start to save and practice doing a business while he's still young.
