Is it right?

Dear Readers,
I've wanted to publish something for years, but my parents never cared about it when I was little, and now I'm really busy... but a few days ago I've suddenly caught a new idea for a book... I've thought of writing on my childhood, but not use my name in there or any of the other people's real names... I don't know if I should ask my friends that were with me in my childhood if it's OK to write about them too in my book... I'm too shy to ask them that... Is it right not to ask them? Should I write the book without asking them? Should I not write the book or publish it at all because I'm such a shy person? I really don't know... Do you know what I should do? If so- please write it in your review on this letter...
Thank-You,
The-Author.
