Mature workers are less impulsive, less reactive, more creative and more centered.
At the center of your being you have the answer; you know who you are and you know what you want.
What is the difference between focus, concentration and centered.
When you are focus or concentrating you are alone. Means you use your mind. Most of the time you feel tired also.
Centered is like dance which happens with the rhythm of music. You are aware of outside world with respect to yours. After the dance many of you might have felt that still you are full of energy. When you are centered you are at your navel. This is like you are in the womb. When you are centered you are more like embryo/fetus, which is always relaxed.
