The Butterfly Effect, simply put. Everything you do effects everyone.
Think about how many people have effected your life. Do you not think that what you do is not just as influential?
.. They say when a butterfly flaps her wings it is felt across the oceans.
Yes, that's huge.
Along with effectiveness comes the responsibility of Receptivity.
This life force is not assertive but more of a timely effect. A quiet contribution is more successful.
