Your comfort Zones Change Them
Stay As You Are.
Your comfort zones are behavioural states of mind that you habitually exist in. They are generally anxiety free, however not always.
They give you a sense of security but are very limiting as they will only give you an average or steady level of performance. With nothing much changing or happening.
They also effect your personality and contribute to your current life style and level of emotional stimulation. Very successful people regally expand and step outside there zones, as they understand that if they keep doing what they have always done, they will continue to get the same results.
To grow. learn and experience new things you have to experience and experiment and play with new emotions and behaviours and learn how to respond in these states.
Some examples of comfort zone expansion, may be.
A recognised need to leave an unsatisfactory job however your fear of doing it would result in losing your sense of security.
Getting out of a distractive or unhappy relationship.
To step outside and experience new things will cause some anxiety or stress at first, but hay that's part of life. Get over it. Or you can stay as you are.
