121. Don’t spit the dummy ever. Even if you have been given out and you are sure you are not out, or if you’ve got someone out and they’ve been given not out – it happens to everyone. In the long run bad luck and bad decisions against you will even out against good luck and bad decisions in your favour. (For this reason it is argued a batsman should never feel obliged to walk until officially dismissed by the umpire even if the batsman himself thinks he is out.)
