I have my doubts about...

I have my doubts about destiny, I always thought that everyone has a story, and that people who come into our lives is for a reason, that place and the family in which we live is not coincidence. Some people say that the destiny does not exist and that to achieve something you have to work for it. I think that there will always be things that we cannot change.  My mother always told me that the destiny is luck and luck doesn't exist, I think that actually it is not luck, is just that we have a history and a reason why we are in this world, in this moment.
