I've wanted to write all my life. I have the stories, the time, the ability, and nothing is in my way to write my story. Why am I not writing?

Well it can be several things. Charitable suggestions first.

First, you’re overwhelmed by the sheer amount of work it is going to take to write an entire book.

Second, you’re afraid if you start you’ll find out you are bad at it.

Third, you are afraid no one will like your work.

Fourth, you don’t really know where to start.

And now the uncharitable:

Fifth, you don’t actually want to write, you want to have written. You want the product and the “fame” without actually doing the work.

Only you know which of these is true. There are solutions for all of them but the fifth, because while AI could do the work for you, AI is notoriously bad at writing anything but technical articles.
