For the most part your comfort zone is a reflection of your self-image and how you think and expect things should be.
When you are in an uncomfortable situation, or one that doesn't fit your expectations, you usually do whatever you can to make yourself comfortable again.
For many people, even if they are unhappy or unfulfilled, their natural inclination is to stay within the comfort zone simply because it is familiar and safe. Many stay in jobs, relationships, and situations that have long since lost their relevance only because they are afraid of the unknown. The truth is that security does not reside in anything outside of ourselves; instead, it lies within us.
Unfortunately, if you choose to remain in your comfort zone you will never find out what your true potential is or what you are capable of achieving. Nor can you really succeed at anything without venturing out of the comfort of your safety net.
If, however, you make the decision to move beyond the
circumstances, people, and experiences you are familiar with, you move
out of your comfort zone and onto the path of personal development. It
is a path that forces you to stretch yourself, push your limits and
become more than you were.
Of course you don't have to do anything extraordinarily out of character, like climbing Mt. Everest or swimming the English Channel if you have no inclination or desire for it. Stretching yourself does not have to be that extreme.
Anyone who takes a new subject in school, learns a new language, takes up a new sport or starts a new job, operates out of their comfort zone in the beginning.
Ultimately, if you ever want to achieve anything noteworthy or out of the ordinary expanding your comfort zone is a must!
Stretching yourself and expanding your comfort zone is an important part of personal development. Each step advances you to the next level and keeps you on the path of self-improvement.
