You have to be ambitious in life.
Personally, I don't let my head go down; I just keep working hard.
When younger, I was tall but very skinny. When I was 14, I grew and started gaining muscles. So I started doing sit-ups, abs work, press-ups, strengthening my core. I'd do 100-150 reps each day. I knew if my core was strong enough, I would get fewer muscle injuries.
I used to run to school with my brother Jordan. It was two or three miles there and back. We'd do it every day. My parents didn't have the money to buy us bikes. It was nice; we enjoyed it.
People want to see you on the pitch. That was why I left Chelsea. I didn't want to hear people saying, 'Hey, he's doing well in training, blah blah blah... ' The game is what counts.
Obviously, the World Cup is nice and the Euros is really nice as well, but I have always dreamed of the Champions League.
I would rather have a career where I improve year after year than go to the top and then decline. There are a lot of strikers that reached the top before 25, but after 25, they went down.
I feel a lot of people working in the media don't know how much of a student of the game I am. They don't know that if we play on a Saturday, the first thing I do when I get home is watch the other games, watch the other leagues.
