I think we have to believe in things we don't see. That's really important for all of us, whether it's your religion or Santa Claus, or whatever. That's pretty much what it's about.
If I feel I'm not influencing games, not scoring goals or making goals, then that's the time I'd pack it in.
I imagine like most of us that I'd like obscene amounts of money but the people I met and worked with who have those obscene amounts of money and have obscene amounts of fame have awful lives. Really. I mean hideously compromised lives.
