We hunted the same property. He limited out in two weeks. I never even got a shot. It is hard not to feel like I'm doing something wrong when someone right next to you is successful..
Hunting near someone who is having a lot of success can get in your head. I started paying attention to my own choices instead of comparing how I was doing to others. You can lose confidence quickly if you keep score like that
I used to hunt with a guy like that. It turned out he was getting there earlier and staying later than I was. Once I changed my timing, my luck changed too.
