You can do both....write books and getting out there living your life.
I must agree most books have been pictures, but picture books do sell more than fiction. If a book is soley about you, your own experiences, then no doubt that book will take some time to write.
If you have friends to chip in with some fiction then a book can be put together very quickly.
As for all this stolen, grassing, and whatever else has happened.... really lads....it's fecking funny reading
