Religion is for people who are scared to go to hell. Spirituality is for people who have already been there.
I'm just glad that I'm the musical equivalent of a character actress, because blues singers can keep singing and having an audience at 35, and someone like Madonna's gonna have to find something else to do, 'cos I don't care how pointy those bras are that she wears, they're still gonna look a little odd when she's 55!
I've been lucky enough that I can gather all sorts of experiences and find inspiration by traveling around and by spending time with people I admire.
I do feel my loved ones that have passed on; I feel them looking over my shoulder... So yeah, that's pretty profound, when you're not expecting it, you didn't particularly believe in it and then it just sort of happens too often to ignore.
Sometimes I'm more true when I'm up onstage than I'm able to be in my regular life. It's not as exciting to be at home, but I've got to learn how to make that work, and then I will be an ordinary woman.
In 1967 I entered Harvard as a freshman, confident - in the way that only 17-year-olds are - that I could change the world. My major was African Studies, and my plan was to travel to Tanzania, where President Julius Nyerere was creating a government based on democracy and socialism.
Sometimes I don't go into the studio for quite a while because I haven't found enough good songs. They have to have a certain caliber and connect with me because I'm going to be playing them for the rest of my life. I start off with a circle of friends whose songs I love anyway.
Distribution has really changed. You can make a record with a laptop in the morning and have it up on YouTube in the afternoon and be a star overnight. The talent on YouTube is incredible, and it can spread like wildfire. The downside is that it's very hard to convince the younger generation that they should pay for music.
When you find a song that you love, you just have to do it - why would I try to match it? When I wrote more of the songs in the '90s - 'Nick of Time' and other songs I was surprised I came up with - it was because nobody else was saying what I wanted to say.
The consolidation of the music business has made it difficult to encourage styles like the blues, all of which deserve to be celebrated as part of our most treasured national resources.
Nobody taught me to play bottleneck. I just saw it and taught myself. I got an old bottle and steamed the label off, put it on the wrong finger, I basically did everything wrong until I met some of the Blues legends early in my career who taught me another way. I didn't have anyone to tell me women didn't play bottleneck.
People say, 'Gee, you don't really do political music.' Well, I sing a lot of songs about how men and women and lovers treat each other, and none of us want to be talked down to or belittled or ignored or disrespected... So I'm proud to be a feminist.
I'm sure I would have been considered a more significant artist if I was a singer-songwriter. It's just not the way I roll. I love being a curator and a musicologist. People write me letters and thank me for turning them on to Fred McDowell and Sippie Wallace, and that's partly my job this time around.
Playing guitar was one of my childhood hobbies, and I had played a little at school and at camp. My parents would drag me out to perform for my family, like all parents do, but it was a hobby - nothing more.
