Is the Main Character, Boll Brooks, Autobiographical?

The last three chapters came about in my brain write after i'e finished the chapter before. I love to make up interesting fictional characters and and send them on an adventure. The most important thing that's autobiographical is kind of what happens to him in general, in that he makes mistakes and gets frustrated and learns some things. When i write bo i don't know how the story is going to end when i start it. I really follow my nose.
