I ( loosely ) concentrate on 4 things: form, arrow to body alignment, anchor,release. Most importantly also is to FEEL the shot and to mentally SEE the shot and FOLLOW THOUGH. Many other things come into play of coarse... bow arm extension,grip position, firmness of grip, position of release fingers, the list go's on, but work for the FEEL of the shot while developing consistency. I said LOOSELY.....concentrate but relax, relax, relax. Think more about what is going right, not what is going wrong! For shooting practice I shoot 3 arrows. For hunting practice I shoot one.
