Never believe anyone who says we cannot change. Vision is one of the secrets of personal transformation. We are all artists, our mind is the arena of creation and vision is what we are constantly creating.
What is your vision of yourself today - patient, relaxed, positive or tense, tight and negative? What do you prefer? So be creative - what does patience look like, feel like, what are you doing that is different when you are patient and you are expressing your power to ...wait?
Always start with vision not action. See it and you will be it. Be it and you will do it. This is how we create our own life.
