Learning how to be a successful salesperson is a key to lifetime prosperity. Have your child assist you with a yard sale. She can sell certain possessions that are no longer important in her life. Since she already knows the positive aspects of the items she’ll sell, it will be easy for her to feel comfortable pointing out their attributes. Not only will she earn money to save for the future, but she’ll also become comfortable with the process of selling, which will yield untold dividends in the years to come.
