Life is such a "funny" thing, you know?
You see the lives of other people and you go, "Hey, I wish I had that" and so on. We also wish and hope for things that seems so far away from us. And somehow, we always feel it's unfair that we are given this life that we are living.
Should be really be thankful that our lives are better than others? Or should we be upset our lives are not so great as others? Majority would feel the former is that we should do, but how many of us actually do what we feel? Because I believe most of us feel the latter instead of the former.
At times, you do not want to feel upset at all but as humans, we feel what we feel and we do not really have any control in how we feel (unless you believe the humanistic approach to human personality which basically says we control whatever we do, WE have a choice). So, how do we get over this?
The stereotypical response would be, "Don't get upset" or "Move on". However, this is not as easy as it seems.
So, in the end, this is life.
