Do I R?E?A?L?L?Y? have a BOOK within me?

I am a public speaker and a teacher. I believe that I can be innovative, creative, clever and inspiring. Yet, Would all of that equal an indication that I could be a successful and appealing author?

My fear is that any book I'd attempt to write would be Snoop-ish- A "Dark and Stormy Night" type of tome! So, What do you think?  Could I actually be a successful author?
