Lächeln - a book

Now i'm starting to write a book, maybe it's gonna be a mini pocket book, because I am writing for the first time and I don't think i can write a 200++ pages book.

The book is about how we can live more happier with smile. How smile can change your life, how positive thoughts can bring you to the absolute happiness of life.

I'm writing it in Indonesian, if it were successful, I would write the english one, too.

Note: "Lächeln" means "Smile" in german (verb).
