Cut your trigger finger off and gouge out your dominant eye!!! Soon you will want to shoot, and won't be able to. Then, you will think about how dumb you were for not shooting when you could have!!!
If your having trouble getting those red gumballs to group....try a mag primer....hahahaI bought myself a slingshot $5 and a bag of gum balls $3 box of beer$15 sat on the patio and practiced my drinking and shooting the cans. Can't beat that kind of fun for only $23. Plus it is a lot harder than one might think.
