I always had a very strong sense of responsibility, so the minute I started to work in fashion, I was always tremendously serious-too much sometimes. Of course, you can make a lot of mistakes in this job-I still do-but you need to limit them as much as possible. When you're responsible for such a huge company, you cannot play too much. In the beginning, I was working 20 hours per day and I was going crazy. I learned that I needed to delegate and to trust the people around me, but there is still not one element that I don't see or edit or discuss with my people.

You need to reinvent yourself every day when you are doing creative work. I always say that the moment I feel I'm at the top of the mountain and I cannot do more, I would be finished. So that's why I always feel the earth quake beneath my feet. I always feel myself on the fire. Because I think this is something that gives you the right adrenaline to work and go forward in your professional life. I have reinvented myself, believe me, many times in my life!

I'm used to spending a lot of time with my team. They're not only collaborators, they're also friends. It's the biggest part of your life that you share with these people. But sometimes being on the top of this pyramid, you need to be a little bit tough. This job is becoming very tough for every company because of timing. You don't have the time to finish the collection before you have to think about the next one. But I am never loud. I don't like to scream. So we are all working hard, and sometimes you need to reassure them.

Venice never quite seems real, but rather an ornate film set suspended on the water.

I have to tell you, a few people had very controversial feelings about what I was doing with Gucci at the beginning, and now, after a couple of years, they are changing their minds. I want to give journalists the time and space to know me and what I'm doing better. But it's not a priority for me. At the end of the day, I am not an artist; I am not doing a performance; I'm doing things that need to be sold. And I know my job.

I like tough relationships. I think relationships with conflict are good for you - you learn. But you can't listen too much. I have a strong point of view, and it's important that I fight for my ideas.

I think the simplest way to break the ice is probably to try playing on the same level, to discuss everything in normal life. So, for example, with Katie Holmes, we just spent one hour talking about her daughter. Or with Madonna, when we were working on the event in New York, we spent hours deciding every single aspect together, from the dishes to the flowers to the cards.
