The number one thing is misread intentions. You assume someone has ill intent toward you and you don't check in on those intentions. Then a narrative forms in your head, and that's when you start spiralling.

They talk about Steve Jobs having a reality distortion field…. but all the entrepreneurs I met who achieved great things had that. They all had a wilful denial of reality… against all evidence to the contrary they had to believe they would succeed.. that's ultimately what entrepreneurs do.

The industry is so big that it's difficult to give a general read of its state. It's a bit like saying 'what's the state of the global banking industry?' You could do a broad-brush and say that the banking industry is full of corrupt individuals intent on defrauding the world, or you could say that in some markets banking is doing very well- and in others it's doing terribly.

This is nothing to do with the 0.000001% who go on to be professional fighters – it's about the 99.9% of people who train because they enjoy it, and connect with it – and who apply the lessons they've learned to deal with the setbacks, failures, victories, challenges and tests they're going to get in work and life.

Participants in each market, faced with threats, had to put competitive behaviour aside and realise the strength of collaboration.

My learnings came not only from our successes, but a lot of the key learnings came from failures. When you do experience failure rather than to run away from it, you have to sit down and do a good post-mortem and learn from your failures.
