To get more in life you have to become more. Outside of winning the lottery or claiming a multi-million dollar inheritance, you can't expect to have more by just standing pat and doing nothing. In order to change your current situation you have got to do something different in order to have something different. It is of vital importance that you expand your comfort zone. Your most cherished dreams reside on the outside of it.
As an example let's use the problem of being stuck in a dead-end job. Let's say you want a better job but no company is hiring in your city. Rather than limiting yourself to your current city explore available options in other cities. I can hear it now. "But man you don't understand, I can't move. I don't want to uproot my family." Well, is that the reason or is it an excuse that you have been giving to yourself in order to rationalize away the fear that you feel? Sure it's scary to change but on the flip side of your fear lies opportunity.
When we step out of our comfort zones we are rewarded in countless ways. Our confidence gets a boost. We learn new skills. Our comfort zone gets expanded. All of these benefits set us up to live life at a higher level and experience the success that we desire.
When we expand our comfort zone we find that it is easier to go after the big goals. When we go after enough big goals we are certain to hit our fair share of them. It only takes the successful achievement of a few key goals to change your life permanently for the better. Even when you fail you keep possession of the valuable experience and skills that you gained in your pursuit. These attributes can be used again and again throughout life. You can even use the wisdom gained to pass down knowledge to your children, not to mention setting the proper example.
Rather than waiting for circumstances in your life to change step out of your comfort zone and realize the boundless possibilities that await you.
