witch part do wewe think is the most important of being a writer ?

yeah wewe need to have passion for what wewe do but with me the most important part is the creativity. many people want to read a book that is both original and creative. that is what i look for in a book.

To be able to communicate with readers effectively.

It is true that a writer must have passion and patience another important thing of being a writer is that a writer must believe in her/him self

Well, there's lots. Passion, patience, dedication, perseverance, determination...they all are important. But creativity is probably the most important.
