One of the first drawings I did in Paris - I wasn't thinking of doing drawings, but somehow or other, I kept drawing - I bought a hyacinth flower with a lot of leaves, just to make me feel like spring.

Shading is more like copying. And certainly I do copy, but I'm making drawings, and I'm not trying to make them with the shading.

When I see a white piece of paper, I feel I've got to draw. And drawing, for me, is the beginning of everything.

In Paris in the late '40s, I started making my first reliefs. They are separate panels. I wanted to do something coming out of the wall, almost like a collage. I did a lot of white reliefs when I started because I liked antique reliefs, really old stuff.

Shape and color are my two strong things. And by doing this, drawing plants has always led me into my paintings and my sculptures.

I just feel like I can live on. I hope I can reach 100. I think today if you just keep doing, keep working, that - maybe that's possible.
