Don't ask what the world needs. Ask what makes you come alive, and go do it. Because what the world needs is people who have come alive.
We are all joined in the holiness of the mind that God created. I therefore never consider myself alone in the silence. I'm 90 and live alone in a four room house surrounded by open space. I have no T and have always luxuriated in silence. The exterior silence is here. The i8nterior silence is a work in progress.
