What do I do now that I have self published my own novel?

[A Thousand Miles]

I am 15 years old and I wrote and self published my own novel called A Thousand Miles. I got it edited as well as I have purchased the copy rights for my book. It is now in the public library in my home town and school. I have also been given the opportunity to get my own book signing at my school. I also am in the process of putting it in a book store out side of the town I live in. I'm getting interviewed Saturday for our local newspaper and I was written about in an article for ARISE! I was told that I wouldn't even be able to write my book and I have accomplished all this. Now my question is do you have any other ideas as of what I should do?!
