Swearing is industry language. For as long as we're alive it's not going to change. You've got to be boisterous to get results.
As a soccer player, I wanted an FA Cup winner's medal. As an actor you want an Oscar. As a chef it's three-Michelin's stars, there's no greater than that. So pushing yourself to the extreme creates a lot of pressure and a lot of excitement, and more importantly, it shows on the plate.
You don't come into cooking to get rich.
Find what's hot, find what's just opened and then look for the worst review of the week. There is so much to learn from watching a restaurant getting absolutely panned and having a bad experience. Go and see it for yourself.
