Do not limit yourself within the confines of what you may know to be comfortable. Often a comfort zone is anything but comfortable in the end. Sometimes a new horizon can shift you into an expanded, wider place. Do not limit yourself and do not let anyone else limit you.
I am not saying to forsake responsibilities. What I am saying is to reevaluate your life and if you know you are called to more, then pursue that. To remain in the narrow confines of your own or someone else’s limitations is to severely diminish your life potential.
