To think anything is impossible is to limit the creativity of the Universe. Time & time again throughout history everything that was once impossible has been proved to be possible.
The potential for everything has always been, it has only been our minds and beliefs that have caught up with the infinite potential that is right before our very eyes.
Anyone who says anything is impossible is dead wrong. You can create any kind of life you want. The magic happens with an open mind, humble attitude and persistent effort. Trust yourself and you'll be amazed at what IS possible.
