Injustice In This Life

Have you ever heard this statement ?
"Life is not fair".
I bet all of you must be ever heard this statements many times.
Do you agree to that statement ?

We must be feel that statement especially when you're comparing your life to others.
Actually I admit it might be a wrong thing when we comparing our life to other people's life, because there's must be someone who has better situation than us for each aspects.
It's not something that actually we have to done, because we will feel less thankful because of that.

However, as a human, there must be a time for questioning all the things.
When I saw lot of people have a good life by their hardwork, I don't wonder and think anything strange about it, since they deserve to got it based on their great effort.
but how about if it was not because of their big effort ?
Still, some random thoughts ever come up to my mind.
How can be there's someone who has a genious brain since they were born but there's someone who has low IQ and has a difficulty to understand many things ?
How can be there's someone who born wealthy since they were born and got everything they want while there's someone who was born in poor family and has a very hard situation since a little age ?
How can be there's someone who has a chance to make so many friends and have a normal youth time while there's someone who could not spend their young life as a normal teenager ?
How can be there's someone who can always see and chat with their love for every minute while there's someone has a very difficulty to have only such a little time with the person they love ?
How can be there's someone who is appreciated so much by lot of people because of their status while there's someone got rejected and underestimated by many people because of their appereance ?
How can be there's someone who has a happy family and there's someone who don't know their family since they were born ?
How can be there's someone who was born perfect while there's someone who was born with disable physique ?
How can be someone who do a unhealthy lifestyle have a good health but someone who run healthy lifestyle suddenly got incurable disease ?
How can be there's someone who has so many people that care and always ready to help solving their problem while there's someone who got no one person who cares about their problem ?

Is that a justice ?
Why can be those so much difference in this life ?
How can be life become so cruel ?
Honestly I don't know why at this world that's so many stories and injustice like that.
One thing that I know is the way to respond it.
Maybe we must not ever our life to other people, since it can make us feel very angry.
Just keep a humanity in your surround as much as you can, appreciate and show respect to every people, including the people who (maybe) lower than you.
Well if you're still questioning "why life isn't fair" ?
I think there's one best answer about it :
Because That's How Life Supposed To Be Goes By.
