You don't. I have hunted w/my BIL for 8yrs and has yet to take a deer. In yrs past I have done all the scouting and placed stands. The last 2yrs I figured he would (and I) feel more fulfilled to help scout and put up stands. We put up a stand this yr and I'm sure he will take his first.
I have found if you want to get someone into hunting then convince them to help w/scouting and placing stands. B4 my BIL helped the wife did and she was hooked B4 she spent a minute in a stand during season. Now I have regular help, and also have another 2setsof eye' in the woods. Trail cams, nope just enlist the help of friends and family...... and just enjoy your time in the woods. Personally, I feel proud to have any hand in the harvesting of mature deer. Even if its with someone else doing the killing[8D]. They may get a rack and it may be bigger than mine but I get a the memories and a pic of the animal. I also remember to keep some stands for just me.
