Observe yourself as you go through a typical day. Stuff happens to you. As it does, you immediately judge it and label it. Dozens of times. Hundreds of times. So often that you no longer recognize that you're doing it. It is a deep-seated habit.

I don't believe that being an inspiring leader is a goal that you can aspire to. It is a by-product.

We, as individuals, must be responsible for our careers with the goal of reaching our highest potential. The job of a manager is to tap into that energy that's already there.

Think of the universe as a benevolent parent. A child may want a tub of ice-cream and marshmallows, but a wise parent will give it fruits and vegetables instead. That is not what the child wants, but it is what the child needs.

I think Sam Smith's dad got a huge loan or something to help his career. Those things can help artists get attention, but I guess my song 'Say You Won't Let Go' proved it's about the song.

When I look back on my career, from the hard work I put in, I got everything I deserved.

When I left West Ham in 2004 there was a chance of them signing me instead of Spurs, but it isn't something I think about too often. I've been spoilt during my career.
