Climbing to the top demands strength, whether it is to the top of Mount Everest or to the top of your career.
I'm not a guy who curses very much in my personal life. When I curse it sounds like a kid trying to be cool. But I think there are quite a few people, my father being one of them, who use curse words rather eloquently.
It's very important to go through periods where you sound just rotten and you know it, and you have to persevere or give up.
