"My blue belt was defined by the word 'insist'. One of the most important things I learnt as a blue belt was that I had to always insist on positions, believe in them and execute them with a 'full heart'. If I'm going for a pass, keep pressuring until I've established it; if I'm going for a choke keep holding until my opponent taps. Never stop until the position has been conquered."
