Losing To Many Good Images

Focusing mistakes (with both the Banarma and Linhof), movement errors are costing me to many negatives. It is so disheartening to have the exposure, the pose, the feeling right in a photograph and then screw up the focus some how or have subject movement. I have to keep working at it, keep trying but its so depressing to almost have it and then look at the neg under a loop and see its out of focus. I need to improve my camera skills, I make to many mistakes. I feel down and lousy, am going to develop another 10 sheets then go to bed, another 12 hour nightshift awaits, the last of 7 work nights.
