Engineering is a fantastic base for any career.

What you learn at university is a good discipline but has little relevance to a real job.

I've always found diversity more interesting than specialisation. I like mixing it up across years, within days, within weeks - that's what stimulates me, gives me energy.

I switch on and off very easily; I'm inherently lucky in that sense. I sleep well.

Each of my career decisions has been very much about doing what I wanted to achieve in the role and then finding another challenge.

My day, normally speaking, is: I go the gym in the morning, I go and work for 10 or 12 hours, I have dinner, I go to sleep.
