It took me 35 years of being involved at a decent level of football to become manager at a great club like Celtic.
Fitness is a curve. You can be Lance Armstrong, or you can be really out of shape at the opposite end. People enter the curve wherever they are and then they can move up the curve, by better nutrition and better exercise.
I'm a better coach now than when I joined Celtic. The longer you stay in any job, the better you become. If you lose your drive, your enthusiasm, your imagination, that experience is no good.
I did think there were one or two referees who had a personal thing against me. It wasn't them versus Celtic - it was them against me! I just think they wanted to take me on.
People talk about footballers and they get a bad press when not all of them deserve it.
