Look at it as a sport/hobby. Not as a "I've got this concealed gun in case the worst happens. There's a bazillion to one chance that you'll ever need it in a defensive manner. If you treat shooting as a sport/hobby, just like if you ride a bike or play softball, then you'll get familiar with the thing, how it works, what your strong and weak points are, where the bullet goes when you press the trigger.
That and probably don't look to MS magazine for shooting tips.
