What I've learnt is to be in the now. It's something my mum has always said to me, and when I read a book called 'The Power of Now' by Eckhart Tolle, I realised just how important it is.
Even though I haven't released a song since 2010, I have still performed, so I don't feel I have been completely away from music. I have been away on a mainstream level, of course. But releasing a single this way - on my own independent record label - is more fun.
People worry about their looks going, but go deeper, and you realise you know yourself more and you're more comfortable in your own skin and more settled within yourself, and that's a really great basis on which to live your life.
I've always been taught that life is a series of chapters, and it's all about moving forward and not carrying around baggage.
I'm not one of those regimental people who never eats certain things - that's not life. You've got to live; you've got to eat what you want and treat yourself.
I have definitely had times in my career where I have wondered whether I have had to work a bit harder, prove myself more, but I would never want to be in a position where I am saying, 'Oh, I did not get that job because of my race.'
I was the only mixed-race girl in my school, but for me, that was a positive thing; it made me unique. If it wasn't for spending time with the black side of my family, perhaps I may have felt like an outcast, but I never did.
I knew I always wanted to be my own boss. My mum would say I've been my own boss since primary school. It was probably always my destiny.
When I saw Neneh Cherry singing on TV, I was so glad that there was someone of the same ethnicity - and with the same curly hair - for me to look up to.
I am constantly thinking of different ideas and formats for TV shows. I am in a place where anything is possible if you want to do it.
I started out as a duo with Mis-Teeq's Sabrina Washington, and we worked for four or five years before signing a record deal. I had no money, and I was taking part-time jobs just to earn the train fare to get to rehearsals.
One day, I would like to have my own chat show. Oprah is my idol because she uses her platform so responsibly.
There were very few British black women on TV or in music when I was a teenager; when you're growing up, you need someone you can identify with. I remember at Christmas being bought a doll that didn't look anything like me, so I threw it away.
Sometimes in life, when bad things happen to us, or things aren't going our way, or we're faced with a challenge or a problem, it's how you look at the problem; it's how you do it to change your mindset, to dilute the negativity.
There still aren't many black women on prime-time TV. Times are changing, but it's interesting: we're in 2013 and still experiencing firsts... Hopefully, in the next 100 years, things will balance even more.
I'm not doing a 9 to 5 job, so every week is different; one week I might be at home for three or four days, and another week it'll be busier. That's the beauty of my job.
