Understand that what is inside of you, what you imagine your world to be is what your world can become.
We are born screaming for air. We die gasping for breath. And along this fine journey we are surprised by the many airs that are let out of our sails. I know not why we are surprised when what we percieve as trouble comes calling at our door, for every step of our life is fraught with risk. As a child learning to walk, to a youth learning to ride a bycycle, to a young adult learning to drive a car, to a grown up trying to navigate a relationship, we experience challenge and change.
When you understand that the power to achieve what ever you want to achieve lies within you, then no one or nothing can stop you from achieving your dreams.
