I have always promised myself and my wife that when I don't enjoy it anymore, or I can't handle the stress and the pressure that comes with having such a high-profile and top job - or my energy levels starts to fail me, or my enthusiasm starts to be dented - I won't prolong my career longer than I feel I should.
A lot of young coaches who respect the fact I have been doing it a long time, that is often their question: 'Does it get any easier? Can you relax more during the games? Can you take it all a little bit more philosophically and put it more in perspective?' The tragedy is that I have to tell them, 'No. If anything, it gets worse.'
