Agnes Martin said this quote

I don’t believe in influence. I think that in order to be an artist, you have to move. When you stop moving, then you’re no longer an artist. And if you move from somebody else’s position, you simply cannot know the next step. I think that everyone is on his own line. I think that after you’ve made one step, the next step reveals itself. I believe that you were born on this line. I don’t say that the actual footsteps were marked before you get to them, and I don’t say that change isn’t possible in your course. But I do believe we unfold out of ourselves, and we do what we are born to do sooner or later, anyway.
