I wrote an article on how running a business changes as they grow up. You can read it
here. I've paid my children in the past to do basic tasks including shredding but as they grow I'll teach them more about business. I already have my 10 year old asking about starting a business and what he could possibly do. The life skills and business ethics my children are learning will definitely set them up for life even if they choose to become an employee rather than an entrepreneur.
