When I was 11 years old, I was playing for the Lierse youth team, and one of the parents from the other team literally tried to stop me from going on the pitch. He was like, 'How old is this kid? Where is his ID? Where is he from?'

Ever since I was six or seven, I wanted to be a professional footballer.

What I would like most is to play in the Champions League and try to win the Premier League once. Or better - a few times.

If you don't have ambition to be one of the best, someone will always come and take your place.

With my quick success, I didn't have time to learn the ropes of the music business. Because my first record was such a hit, I was terribly spoiled and I thought I couldn't do anything wrong. I was also desperate to make tons of money because of my responsibility to my daughter. And there was no longer any joy in making music.

I get hired by companies to hack into their systems and break into their physical facilities to find security holes. Our success rate is 100%; we've always found a hole.

If your goal is to make money, becoming an entrepreneur is a sucker's bet. Sure, some entrepreneurs make a lot of money, but if you calculate the amount of stress-inducing work and time it takes and multiply that by the low likelihood of success and eventual payoff, it is not a great way to get rich.

When entrepreneurs talk about their success, they rarely talk about luck. I think that's because most of them think the concept denigrates the hard work and smart thinking they put into their projects. But luck is a huge part of any successful business.
