I never seen him drive personally but I've read up on him. I love this quote from him, amazing intensity; life and work philosophy.
“The harder I push, the more I find within myself. I am always looking for the next step, a different world to go into, areas where I have not been before. It’s lonely driving a Grand Prix car, but very absorbing. I have experienced new sensations and I want more. That is my excitement, my motivation.” Ayrton Senna
