Why is it that I seem to invite shady people like flies to honey? I’m honest and hardworking, and I expect and assume those around me are too. I keep finding out just a minute too late that I am wrong. How can I improve my ability to judge character?

I’ve prayed many times for discernment, I wonder why I’m not receiving this gift. I’m sure God is trying to hand it to me, but for some reason I’m just not getting it.
