Darren Campbell, the British Olympic sprinter, was my sprint coach at Middlesbrough - yet the best advice he gave me was to slow down. That might sound strange but he said: 'You have too much speed - you don't always need to run at 100 per cent.' I was used to running flat out every time, but he told me, 'You know how quick you are, slow down.'

There are times when you're being judged on your appearance and you're not feeling your best self. It hurts, but as I always say, I try and be 100 percent myself all the time. So if I'm rejected, it just hurts that little bit less because at least I was myself.

I had written rap songs in the early '90s and even did a couple homemade rap songs with my brother in like '88 or '89, but it was just like... I don't even know how to say it. Just plain rap. I was just rapping about whatever, there was no real style or direction, it was just semi-braggadocious rhymes that probably imitated 100 other rappers.

The reality is that in a tech environment that is 90 percent to 100 percent male, it's not super-encouraging for females to be successful. It's just a lot of things that contribute to that: things that people do or things that people say that they may not realize have unintended consequences.
