My father was unwell when I was 11, had a stroke at 14 and died when I was 18. My mother going to work at seven in the morning and coming back to look after him and me and my brother left its mark on me.

What I've learned in my career is that it takes the same amount of effort to build a $10bn company as it does a $1bn company; you as the entrepreneur are going to put your entire life, your entire effort into it.
