All you will ever need is already present in your life
Whatever you desire, you can bring about. There is no waste in the Universe, and to give you something you dearly want without also giving you the ability to make it happen would be quite wasteful!
So if you have a Calling, you also have the means to make it happen!
You create your own reality
You do that through the thoughts you think
Beliefs are thoughts you keep thinking
So you basically create what you believe, if you are aware of these beliefs or not
You can change the thoughts you think, which, over time, changes the beliefs you hold
Meaning, you have control over what comes into your experience!
