The historian must be impartial, but not indifferent.
At twenty-one, I was a divorced single mother. At thirty, I was struggling to feed my children. At forty, I was starting over in a new country. At fifty, I was rebuilding my career. At sixty, I walked the runway at Fashion Week. Life begins at every age—if you dare to make a plan.
I have already carried out my duty. I have proved the Poincaré conjecture and I have nothing more to do in mathematics.
