Mark Sanborn is an author and speaker from whom I have gleaned much wisdom over the years. One of the things he has said is, “You acquire much of the thinking, mannerisms, and characteristics of the people you are around.” It happens without any conscious effort on our part. Look at your circle of friends. I’ll bet if you tried, you would identify habits, dialects, and preferences you did not have before you began hanging out with them.
It’s what bonds people together in a unique way. Relationships thrive or die on whether this form of bonding occurs or not. Of course, not all the traits you graft on to yourself will be positive. There is as much opportunity to be worse for knowing your friends than there is to be better for it, so choose your friends wisely.
