If you have love in your life it can make up for a great many things you lack. If you don't have it, no matter what else there is, it's not enough.
The only time I think about life beyond F1 is when I contemplate becoming a dad. But there's no way that's going to happen while I'm still racing. To be successful in F1 you need to be very selfish in lots of ways and you're away from home for long periods. That's not the kind of father I want to be.
