Because of Destiny ? Fate ?

It is too general. I think it is because of attitude, an attitude of life.
All depending on the attitude, how and what a person wants to be.
What really addicts to his mind and what really encourage him to pursuit what he wants.

When we look at a person's life, how do we determine if he is successful or not ?
The definition of success is too broad and everyone may give a different meaning to it. What does success really mean to the one we observe ? It is probably not the same as what you and I think.

I hate people press their definition of success to my mind. It is nothing to do with victory. It just matters with if we feel we are done with accomplishment and achievement.

I don't like the word "Destiny". It means it is fatal and nothing can be changed.
Isn't everyone living and improving their life everyday ?
We are in a process of evolution ...
There would be worries, terrors, and afraid, but there shouldn't be any fate neither destiny evolved.
