Things don't always go your way in football: there are always good and bad times. At the end of the day, you have to have a positive attitude and a strong mentality and not let any setbacks get you down. And that's what I've done - I've tried to keep my composure, even when things aren't going the way I'd like.
At the end of the day, you are solely responsible for your success and your failure. And the sooner you realize that, you accept that, and integrate that into your work ethic, you will start being successful. As long as you blame others for the reason you aren't where you want to be, you will always be a failure.
Your personal life, your professional life, and your creative life are all intertwined. I went through a few very difficult years where I felt like a failure. But it was actually really important for me to go through that. Struggle, for me, is the most inspirational thing in the world at the end of the day - as long as you treat it that way.
