First master the rg on paper. Second run rg clinics on dudes with 1 day experience. Then run clinics on dudes with 1 week experience. Then run rg clinics on dudes with 1 month experience. Then run rg clinics on dudes with 2 months experience. If you can't run rg clinics on dudes with 2 months experience, go back to 1 month dudes. Eventually you will be able to run rg clinics on all white belts, and that is huge. Keep running rg clinics on white belts until you can run rg clinics on a blue belt or 2. Eventually you will run clinics on all blue belts. Obviously you see where I'm going with this. It's simple, if you can't run an rg clinic on a white belt you surely won't be able to pull any rg on a black, brown, purple or blue. Time, reps, time, reps, time, reps, patience.
