Is being an author that great?

i'm 16 years old,love writing ,i almost do it instinctively.The words flow down and they're just there.But i'm afraid that's the wrong thing for me,i'm afraid that even if i got published and became a well known author would that realy be great...what do u think?..should i die and be sure that there's one soul out there that felt happy or hopeful for reading my books.I know it sounds stupid,but i can't just be average in the one arena i believe i belong in...so what is greatness really?
