You can generally place people in four quadrants: Amiable; Expressive; Analytical; and Driver.
If you want to increase your success of building better business and/or personal relationships, then first you need to understand what kind of person you are among the 4 quadrants listed above. I am in between Amiable and Expressive with some Analytical. Since I know what kind of person I am, I know I need to find others who share my personality pattern if I want the best chance at a successful relationship. Two people who get along in a friendly manner are also inclined to work well together too. So, there really aren’t any negative factors with finding people who are more like you since you’re most suitable as best friends and/or doing business together. This is a perfect marriage that can bring forth wonderful benefits. If you want to sharpen the other personality types that you don’t possess, then make some new friends who fit those types and you’ll be on your way to finding: stress, love/hate emotions, fear, passion play, bitterness, self-reflection, etc. Aren’t relationships fun. My advice: Always be on the lookout for someone who is just like you.
