We live a life of choices. Most people would choose comfort.
Comfort is the familiar and the well-known.
Our comfort zone is our personal area of thoughts and actions within which we feel comfortable and safe. Anything we haven't thought or done, something new, lies outside the parameters of our comfort zone. When we think or do these things long enough, we often feel uncomfortable. And, after feeling uncomfortable, we sometimes get discouraged and tend to give up before ever starting something new. Of course, to accomplish something new, to reach our goals and to achieve our dreams, we're required to venture outside of our comfort zone.
