There is no standing still. Everything is always transforming into or out of form. We are either growing or decaying.

These feelings will literally move towards you the people, circumstances and items needed to achieve your desire.
Your dream must only be large enough to change the way you feel. The best part is that if you take steps towards your dream, you will be met in the middle. You do not need to go the entire distance by yourself.
And remember that doubt or fear will pull everything back. As long as you can "see" it and feel it, know that even though it is currently invisible in reality, it is actually moving and growing towards you.
