Green grass

I've always wondered, why is the grass always greener on the other side? I work so hard to get to the other side and then I find a greener pasture just a little further away.

On one hand, I really do want to be happy and satisfied with what I have. On the other hand, I think its good to make goals and reach them. One of my internal struggles is what to do once I've reached the goal. Its all too easy to whiz past the glory and move on to the next goal. I never give myself the credit due because I'm always reaching for the other side.
