Want to quit?
Nah, no way. Even though I can only do 1/2 of what little I used to do, even though I consider myself a half crippled old fert, even though I cannot lift a hive body, even though I have a crushed vertebrae (wedged disc) in my back, even though I am held together with titanium screws in my bones, oh well, just gotta laugh and keep plugging away. I am Blessed! Humor is intended, its ok to laugh at my condition. Had been around bees since birth, 1950's and I would not know how to cope without my lil buddies I see every nice day. Bees and Van go together very well, perfect fit, I tell ya.
Now, relating to grafting: grafting improves with each attempt. Little things are adjusted that make big improvements in percent success rate. Such as (my previous errors improved) placing larva holder next to the larva to be grafted, rejecting larva that you bumped or rolled. Each graft reveals your ability to improve providing you pay attention to detail. You will get better.
