People probably can not because fate, is beyond our control. I dont really get this but if you mean destiny as in under someones situtation then yeah I guess people have a greater impact than they realize. For example, some people just aren't born lucky, they probably have prepared themselves for success to the point where they have a chance. So, therefore being lucky is more of a mindset type thing, also being fortunate when subjected to random chance. Kind of like if you look at people who have succeeded by their own. They all have this common characteristic in common.
