I am 10 years old and cannot go into any neighbors house, because of my parents. I'm quite frankly very shy to go around selling stuff so what should I do?

Can you do chores for your parents or relatives that live nearby?

At your age you're too young to babysit, you're too young to be hired by anyone. Really, your options are dog walking, shoveling snow, a paper route, all of which would have to be approved by your parents.
