My mother used to have a shop in which she offered very colorful clothes. I liked that from my early days on.

I have a passion for fast cars. To drive them means pure joy to me.

I always set myself new goals. I always want to do better than I did in the past. I always want to achieve things I never achieved before.

We have our ambitions [in Dortmund Borussia], and of course I would love to win some titles after some years of finishing second or losing finals.

Few years ago I did 30m in 3.7 seconds. Whether that makes me quicker than [Usain] Bolt, I don't know! We all know Usain is the best.

At the same time the players around me almost make it an automatism to score goals. We have so much quality and speed on the pitch - the genius of players like Mario Gotze or Marco Reus has to lead to goals.

Last season I scored 27 goals but still lost out against Robert Lewandowski. This season has started very well for me, but again I have some tough opponents, most notably with Anthony Modeste from FC Koln. I texted him the other day: "Keep calm, my friend." I am happy for him to be so successful. And in a certain way it even helps me. The better the other strikers are, the more I have to work to be to be ahead of them.
