Turning good into great: is a wonderful thing in Jiu Jitsu. It is very important however, that you adopt a maximizing mindset with regards positioning. Don't for a GOOD position when a GREAT position is well within your reach. Here, Helena Crevar @helenajiujitsugirl has gotten to the mounted position – that's very good – but she does not settle for good – note how she focuses on walking her opponents arm up into that takes the position from good to great and opens up many submission holds. Take the extra to take your favorite from good to great and you'll take your overall from good to great!
