New Delhi: After 16 years of surviving the Bollywood grind grinding with more hits than misses, actor Katrina Kaif, says one needs to have nerves of steel to be in the glitzy world of Hindi cinema. “It’s not always easy. You need to have nerves of steel to be in the film industry. It’s an unpredictable place and no one can guarantee success. I believe in not taking success to your head, or failure to your heart,” Katrina said. She tags her 16-year run in Hindi films as a beautiful journey. “It’s been wonderful, a lot of hard work but also a lot of love from the audience,” she said.
