It's just, I would say, faith. I had very clear visions of me being a champion. When I saw this picture of Reg Park on a cover, standing there like - as Hercules, from the Hercules movies, I looked at that, and then I looked at the inside and I read the story, and I immediately started creating visions of me standing there on the pedestal at the Mr. Universe contest and me being Hercules and me doing movies and so on. And that created such unbelievable drive and such unbelievable will and discipline, that there was absolutely no stopping me. I mean, I went to the gym two hours every day lifting weights. When I came home afterwards, I lifted an extra hour and a half and did bodybuilding training, and it was just relentless.
