Only when you step outside from what is comfortable and familiar you grow, because you find yourself in a situation you have never been before where you need to react. And you do it. You react, and in many cases your reaction might even surprise you because you didn’t know what you were capable of doing.
Sometimes this acknowledgement will make you feel proud and pleased with yourself, but even if it doesn’t you still will have grown and learn by that new situation and your reaction.
Why then fear the unknown?
Challenge yourself. Discover your limits and dare to go beyond them.
Take the courage to step into the unknown by yourself without waiting for the unknown to catch you off guard.
