Having started feeling blast at the age of 28 and going from green to appointed in 11 months has to be one of my biggest achievements. What I really enjoy is when you see someone that you take under your wing and watch them go from green or experienced and they become a shotfirer under your guidance.
Think one of my biggest achieving is just the knowledge I have learned from side to side taking everything in being able to pass that knowledge on and use what I know to help get the best out of each shot.
