Whatever I turn my hand to, I put in the effort to be the best.
I eat healthily as much as I can - meat, protein, carbs as well. I like my pasta; I like my rice. I like to have that sort of sustenance in me, because I'm always thinking of survival.
I might wake up in the morning and go out for a six- to eight-mile run, and then in the afternoon, I might swim two or three kilometres. The next day, I'll mix it up and do a military circuit. I don't stick to a set programme.
When you're in the military, you teeter on the edge of that line of life and death. The reason you feel so alive when you come through is because you know you've cheated death - and that and the adrenaline rush is addictive, no question.
It's asking that never-ending question, 'Who am I?' which motivates me and takes me on a constant journey of self-discovery that teaches me so much. Will Everest make me more cautious? In reality, probably not.
I had a tough childhood after my father died when I was five, and I had a very difficult stepfather. I want to give my children what I didn't have - a good role model.
When I was younger, if I got into arguments, I'd become aggressive and violent, but I learnt the hard way that was only going to end negatively.
I don't stick to a routine, because I like to mix things up, which stops training becoming boring and helps shock muscles into firing up.
I joined the Marines, passed Special Forces selection, and became a young leader in the military.
