“The grass is greener where you water it.”
I think it is a pretty normal part of the human condition to want more, to look at what others have, where they are at, and think “that must be nice.”
It’s easy to get so caught up in jumping to conclusions about the lives of other people that we end up “watering” that side of the fence.  This causes, in our heads anyway, the grass to be greener on the other side.
But do others really have it better than us?  Better lives?  Better families?  Better jobs?  Better existence?
We’ll never know.  There is no way to experience someone else’s life.
Focusing on the yards of others is a sure fire way let your own yard wither and die.  Besides, we can’t control what other people do with their own property, all we have control over is how diligently we care for our own yards.
Take care of your yard: your health, your family, your thoughts, your actions.
Don’t worry about the grass on the other side.  It’s out of your control, and putting your thoughts there will only leave your side of the fence brown and dead.
