"The grass is greener on the side you water."

Hmmmmm....
I like that.

Except it's not really true. We're talking about the desirabiltity of that which you don't have...the unattainable.
I can set my sprinkler system for 6:30 both times around the clock, feed it miracle grow every day, heck, I could even play it classical music, but no matter how good my grass gets to looking, there's always going to be something I don't have that I want, that looks a hell of alot better than what I have, just because I don't have it.

(Successful) adages become adages because they're true. Come up with new ones, but leave the time tested alone. It's lasted for a reason, that reason being that it accurately portrays a facet of the human experience, regardless of what era it's used in.
Until we've all acheived Buddha nature, I think this one will apply.

Maybe this was just someone's nice way of telling me to stop complaining. They're probably right.
But I probably won't.

It's in my nature to be dissatisfied with my position. Accept it.

p.s. now's not a good time for losing weight
