Boxing, mixed martial arts and tennis are the hardest sports to train for.
Contrary to my image, I do have a sense of humour.
It becomes tricky, and you start to think about the cramps rather than just actually what you're trying to do on the court, which is obviously win the match.
Give it everything you've got. Leave nothing out there.
I'm on the road so much that I don't get to spend as much time there as I would like.
I fully understand that not all of the companies will succeed and that there will be losses along the way, but this is very much the norm with early stage investment.
