Keeping your wife interested in your sport
That is the fastest way to have someone loose interest in what you are trying to get them interested in! Both my Wife and Daughter shoot with me and neither are wimps about what they shoot, 458 winchester mag, and 50 bmg rifles. But I know some people who were turned off to the sport by behavior that didn't give them confidence in the people around them. We all have to remember that we all start from zero, NO ONE STARTS AS AN EXPERT. All the information that we learn comes from those who we shoot with and the people we associate when we are in the field. Our job is to make it as seamless and fun for everyone to learn.
My 2 cents.
