I think the secret is to understand that you still want to be part of the game. To do so, you have to forget all the victories you've managed to get in the previous years and have a great humility. You also need to realise that, if you want to go on, you have to work hard. If you dwell too much on your past successes and say "well, I have won nine world titles and more than 100 races", you'd rather stay home.
