If you haven't then I'm sure you will at a later date. If your mom, Grandma, or even great-grandma started when they were lets say 15, you might inherit that and not start until your 15. But if you don't want to believe that I have two more things to say. I am about 11 years going on twelve and I haven't started yet. My mom staarted when she was a little older. So I might start like her or even later. Also, maybe your just a little late. You may not inherit anything just start your own time. Any of these will be true. Hope this helped.
