Im happy to say that at 62, I think Ive reached that point where stuff doesnt bother me as much, and my gratitude level has gone way up, especially having gone through the loss that Ive had, and losing so many of the great artists that I was close to. They taught me how to see it with a grain of salt and a lot of humor and perspective.

The connection between toxicity and cancer and safe air and water and food, all of that was important all along, as were women's and human rights issues, but the nuke issue and the safe energy movement became really important to me in the mid-'70s.

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.

The generation I grew up in was the beginning of "stand up for yourself," whether being a singer-songwriter or a feminist. In my college years, the feminist movement was really coming to fore, so we wouldn't have put up with guys treating us less than equal.

There's lots of flaws and frailties and cracks in the armor, and nobody wants to put themselves out there as some kind of Joan of Arc because none of us can live up to that, but I'm grateful to be a role model and be respected because I have a whole slew of people, men and women, that I feel the same way about.

I've watched my peers get better with age and hoped that would happen with me.

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.
