You 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. The sport, your rivals, the tyres, your motorcycle, everything changes so instead you need to work more to be stronger. If you don't, you're finished.
