“When the dogs go past that line, I have moved on and I'm now focused on the next week,” he said.
“I'm not worried about what anybody has to say about the dog’s performance. The dog will have run its race and whatever happens I don't let that get to me.
“There are nights after good wins when people ask me why I am not more excited, but I will have achieved what I wanted to achieve and I have never been one for getting too carried away. I certainly like racing at the elite level, but I don't want to be that person who runs around saying: ‘Look what I have got. Look what I have got.’
“That is not me. I just love being competitive and I live that through these dogs.
“No matter what the result, good or bad, I just knuckle down and keep going. Once it is done, it is done and you have to move on to next week, win, lose or draw.
“I don't begrudge anyone who wins races. The people who are doing well at the moment, they deserve the rewards."
Nicholls says he is not a jealous person.
"Anyone who puts in, because I know how hard this game is. It is a lifestyle, but if you put it down to an hourly rate, well, we are not real smart businessmen," Nicholls said.
“It is good when you are at this stage and making some money, but it is pretty tough at the start.
“You have to create your own luck. That's exactly what you have to do - with the hours that you work, the money that you spend and the dogs that you breed. Too many people think they are entitled in this game.
“There is no entitlement, except working your bum off. That is guaranteed and you just keep getting up at 4am and getting home at midnight.”
