What is the most important relationship in your life? Your spouse, your children, your parents- the list of choices can be significant. Although these are all types of crucial, important, and beautiful relationships, they're not actually the most important. Surprisingly, it's yourself.
Before you dismiss this idea as being selfish (it does sound like it!), take a moment to consider the longest relationship of your entire life. Who do you talk to constantly? Who is always with you?
Well, you are.
This level of self-conscious awareness is what makes humans so distinctly different than other animals. You are in a constant relationship with yourself and it's the most critical one because it shapes all of your other relationships. The healthier the relationship you have with yourself, the healthier all of your other relationships can be.
