A few years ago, when I had no work and started believing that films weren't a viable career, I thought of finding another job. I started training and riding horses and got consumed by that. It was a boon in disguise.
Training a horse is above all feeling and trying, according to what you feel, to help the horse and not to force him.
During long, slow distance training, you should think of yourself as a thoroughbred disguised as a plow horse. No need to give yourself away by running fast.
A horse never runs so fast as when he has other horses to catch up and outpace.
I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.'
