"Why would you want to stop racing?” a motor racing team manager asked me once. I’m not that good at it, might be one answer, but he wasn’t talking about me: his was a more emblematic question. 

His point was that people do stop. They come into amateur circuit motor racing with high hopes, and a certain amount of money, but after a few years drift away again, which frustrated him. 

He said he’d seen it too often: people came, spent a lot of money, became frustrated about the amount they’ve handed over and what they’d received for it, so went and played golf or bought a boat, a supercar or something instead.
