honest voices

How do you speak in an honest voice? Isn't a blog mean to be an honest voice? People spend their lives, maybe me, figuring out what it is they are supposed to say. Figuring out what voice they are suppose to speak in, in whatever environment they find themselves in. Don't say this. Don't say it to these people. That might hurt someone. They might not like you. You're at work. Whatever. How do you find an honest voice after a life of that?
