What will be will be ,how true

Hello friends and families i browse through a contest which says how true was the statetement we usually used and believed which says quee sera sera,how true was the statement ,before i proceed i will like to explained to us some things we should all understand which is the fact that the statement its not totally wrong and not totally accepted or correct too, so this shows that my position is in between ,yes based on my psycology and phylosophy i believe what will be will be ,,,after making alot of effort and contribution for it to be! Not that i seat down without any effort and i expect something to be,yes something might be but it might not be what i expected ,it might be something otherwise, so what comes to our mind when we say quee sera sera is anything that will happen will happen no mater what,so what happen then is always as a result of our actions and decision so still we are still incharge of it,lets take for example i want to be rich and get alot of money but i sat down not working not doing anything and i expected something to be, something will sure be which is i remain not getting the money as a result of doing nothing,that doing nothing is a decision too on his own ,so we see now that what will be will be is true but as a result of our own decision, either good or bad it be as based on our own decision, so we can say what will be will be= our decision determine what will be will be
