"Know first who you are and what you're capable of. Just as nothing great is created instantly, the same goes for the perfecting of our talents and aptitudes. We are always learning, always growing. It is right to accept challenges. This how we progress to the next level of intellectual, physical, or moral development. Still, don't kid yourself: If you try to be something or someone you are not, you belittle your true self and end up no developing in those areas that you would have excelled at quite naturally.
Within the divine order, we each have our own special calling. Listen to yours and follow it faithfully." -Epictetus
To know myself, my aptitudes and talents. That is the difficult thing indeed. Once I know who I am don't waste my time trying to fight against it, embrace it.
