I found this fantastic diagram and below quote from the site: Babes in the Backcountry.
From the day a person is conceived they begin to grow.
This growth is supposed to be a natural process throughout our lives, yet, many people reach a plateau as adults where they choose to stop growing. This is a stagnation of our character and learning of essential life skills. But we choose it because it is “comfortable”.
Now think about some of the greatest and most joyous moments in your life. Were they while you were idling in your comfort zone?
There is no magic and no life growth happening if you are only living in your “comfort zone”!
So true.
