When do you know the time has come for change? Is it a flashing neon sign that flickers in front of your consciousness? Or does it softly nudge you in the rib and you have to ask questions of yourself and your life? Could it be some combination of these?
Whatever it is that pushes one towards something else, all I have to say is EMBRACE IT! If you don't embrace it then the change, which is inevitable, will be much more disruptive. Comfort is discomforting to me because I know that I am missing opportunities. Comfort supports apathy in my world and that is a dangerous place from my perspective. How about yours?
