I never really felt secure until I was well into my 30s, because anytime I had success, I would invest in new projects.

I set up this magazine called Student when I was 16, and I didn't do it to make money - I did it because I wanted to edit a magazine. There wasn't a national magazine run by students, for students. I didn't like the way I was being taught at school. I didn't like what was going on in the world, and I wanted to put it right.

You never know with these things when you're trying something new what can happen. This is all experimental.

When you are ready to make your first hires, look for people who understand your passion, want to add to your ideas and can envision ways to make improvements.

I definitely go on gut instinct but it has always had the back up of research and information.

When people warn me against doing something once my mind is made up, I grow increasingly determined to try it.
