You are right no one can understand life, life do things at anytime, this life is something that you cannot understand when it seems you know more about it then you see another thing happened and it will be as if have never seen something like that before.

Life sometimes will be favorable and sometime it will be as if it should come an end.

The best thing is to that, we just have to focus on our goal or focus on our gadget which is success.

We should never allow any challenge or sorrow to affect our dream.
