Does it really matter?

So, does it really matter what am I going to write about?

Hair is a good subject. I have some. Lots, actually. 

No, what I really meant was the musical, Hair. Here it is. 

I could write this book in Russian if I wanted. It would go something like this. 

До свидания – милый скажет, но на сердце камень ляжет
