Arnold Schwarzenegger he never expected to be able to give self-help advice. But in his “fourth” decade of life, he’s collected some of the greatest lessons he’s learned and included them in his new book, “Be Useful: Seven Tools for Life”which will be released on October 10.

“All I try to do is use my knowledge and help other people. It’s the simple things I do that have really helped me get to where I am today“, said the actor in an interview with the American magazine People.

He also said that he always feels satisfied, but at the same time “hungry” for more. “I slept with my first trophy. No one could take that away from me. But at the same time, my other leg was already out of bed and going for the second title of Mr. Universe». (He won three more, followed by seven Mr. Olympia titles.)

Schwarzenegger continued: “So today I feel good where I am. I feel like I’m much wiser. I’m much smarter. I’m not so crazy anymore. I think more about people. I think more about people’s feelings. In your 20s, you don’t do any of that. You are: me, me, me, me. As time goes by, you learn from your mistakes».
