There is a great desire of improving, getting better, that makes me happy. Every time I feel that I am slowing down, my learning curve is getting flatter of whatever, it doesn't make me very happy. And that applies not only as a profession, as a racing driver, but also as a man. Of course, I shall have a lot more to learn as a man than as a racing driver because my career could last not that many years. My life hopefully can go still for a long time... There is a lot to go, a lot to learn, a lot to do still in life. And happiness will come when I feel complete as a whole, which definitely I don't feel today, but I have plenty of time to fulfill that.
