“Sometimes I think I don't know what I'm doing
but I always end up doing what I know.
And what I know may not, I know, be a great deal
but what I know nobody can take,
nobody can take, nobody can take away from me,
no, no, no. Away from me, no, no, no.
I do what I know. Doing what I know.
Sometimes I think I don't know what I'm doing
but I always end up doing what I know.
Away we go, doing what I know.”

"I want everything" http://home.earthlink.net/~2lulah2/everything.htm in What I Want from Life (1934) edited by Edmund George Cousins, p. 108
Context: I don’t know what I want.
Nobody knows — or if they do, they don’t know for long. I mean, you don’t want the same thing long enough for it to be What You Want From Life in capital letters.
Well, maybe some people do. Maybe there's a few simple folks — or maybe a few million, I don't know — who fix their hearts, and their minds, and their everlasting souls on a thing, and keep on all their lives hoping for it. Living for it. Wanting It From Life.
But these are the people who never get it.
