from my Kabbalah meditation:
The grass isn’t greener on the other side. It’s greener on the lawn most cared for.
This does not mean that we should never leave our garden, it only means that we should not think that the patch that we see in another place is greener than ours, and so want/ pine/ argue with ourselves/ search for reasons..... to move there.
We have to strive first to make our lawn the greenest...and best....
