When I was a kid, Mother told me, "There will always be someone willing to lead you astray, if you are willing to follow."
I had followed the wrong lead, which led to her advice. I love Mother for a lot of reasons and one was her wisdom.
I've followed the wrong lead many times but as I matured, I learned discernment. I learned to think better. Knowledge helps one to think better. I had a lot to learn, too. Indeed, I am still learning.
It takes a lot of courage to do the right thing in the face of extreme pressure to do the opposite. It takes independent thinking and discernment to differentiate good from bad. You cannot be asleep and recognize a problem ahead. You cannot be part of the herd and be immune from being led astray. You always have to be thinking and making adjustments to stay the course.
