I miss my kids sometimes and that can get me down when I've been away working, but then I wake up and recognize how incredibly lucky I am. Spending time being down is less time out there achieving and enjoying.
You see Boris Becker, Mats Wilander, Nadal, Pete Sampras - they were all great when they were young. As a coach, you can see that type of talent at an early age.
Before, I guess, mum and dad were everything, but now, in my case, I had two new girls and all of a sudden they're completely dependent on you and there's a third generation. It's a funny shift all of a sudden. You have the babies, you have yourself and then you have your parents.
