When we believe that the grass is greener on the other side, we tend to look at anything but us as the cause of our unhappiness.
Then, we get busy working on things externally to fill our inner vaccum. You may perhaps even cross over the fence into the grass on the other side, get a moment's high, but will ultimately find that the vaccum still exists.
The grass is greener based on where you look. For once, you need to look down at where you stand!
Is the grass really greener on the other side?
