Grass is always greener on the other side?

I believe everyone heard this before, even don't....let me share you what my thought about this.

I've been hearing this in Church, radio even some senior talked to me about this.

Do you really know what does "grass is always greener on the other side"?
Well, from my perspective, it means that things, food, people and everything of someone else is better than our own one.

People use to feel that you are better than they do, the food you are eating taste better than theirs, boyfriend/girlfriend you have is more sweet than theirs, clothes we are wearing are warmer than theirs, so as the "grass" in your house garden is greener than their house.

Why do we always have this thought? jealousy maybe? For me, yeah, I personally think that we always get jealous with what people have. I always tell myself that, I am blessed with what I have, what they are having now, they might work even harder than me, so why should I get jealous? I can have it if I work harder too.

While I'm writing this, lot of things came to my mind.
One of it is, why do you need to wear branded stuff if you don't really can afford it/ you are still using your parents $? I don't know whether this is out of my topic, but I feel that do we have to look rich with branded goods in order to hangout with friends that is rich? Other people might look good in branded goods, but if you force it on you, do you think it looks good?

About couple, I met some girls or guy, always complain to their partner about why they are not getting what other couple get. Like always travel here and there, having gourmet in restaurant,  always spending more time with each other. Do you ever think that if your other half can do it, why don't they? Everyone has their own need, so do your partner. Maybe they have to save up something for future like getting marry with you earlier or what?

I believe most of my friends are working now, they always compare their salary with each other, what benefit they can get from their company. To be honest, I really hate friends that compare my salary with theirs. You are smarter, you are more hardworking, you earn your gold. I have my own plan, my life, why do you need to come and bother me about my earnings and my life? If you want the earning like mine, or I want the earning like you, you can just come and join in my workplace.

This topic can't finish talking if I dont stop here, I have lot of it in my mind, but some might be sensitive, so I keep it for myself =p
Sometimes I will get jealous with what people have too, but thinking back, what I'm having now is good enough? if it is not, I work hard for it.
*p/s sorry if i offended you if you read this, 'I'm sorry' is here for you to collect =x
